CDK vs Tekion vs Reynolds — DMS Platform Comparison for Dealers

Three dealer management systems dominate the conversation in franchise automotive retail in 2026 — but they represent fundamentally different philosophies about how a dealership should run, how your data should flow, and how locked-in you should be.

CDK Global is the market leader by dealership count, serving roughly 15,000+ locations with the industry's deepest OEM integration network and a roughly 30–35% share of the franchise DMS market. Its June 2024 ransomware attack — which knocked dealer systems offline for weeks, paralyzed sales and service operations across thousands of rooftops, and required CDK to pay a reportedly multi-million-dollar ransom — was a watershed moment that shattered trust and permanently altered the renewal dynamics between CDK and its dealer base. Post-breach, dealers who once renewed automatically are now negotiating harder, demanding shorter terms, and actively evaluating alternatives for the first time in decades.

Tekion is the cloud-native disruptor, built from scratch on AWS by former Tesla CIO Jay Vijayan. Its microservices-based, AI-native architecture and modern UX stand in stark contrast to both legacy incumbents. With an all-inclusive flat-fee pricing model and month-to-month contract options, Tekion represents the most architecturally ambitious bet in the DMS industry. But with less than 5% market share and a history of high-profile executive departures and deployment stumbles, the gap between Tekion's vision and its operational track record remains real.

Reynolds and Reynolds is the private, secretive #2 — roughly 25–30% market share — known for premium pricing, 5+ year contracts with aggressive enforcement, and a fiercely loyal installed base that tolerates the lock-in for the platform's operational stability. It operates the most closed integration ecosystem in the industry, maintains the strongest local field support of any DMS vendor for full-ecosystem dealers, and is simultaneously the most difficult DMS to leave — due to proprietary data schemas, legal barriers, and contract structures designed to make exit prohibitively expensive.

At a glance

Pricing ranges reflect industry estimates and dealer conversations. Actual costs depend on roof count, module selection, add-ons, contract terms, and negotiation. Total cost of ownership includes licensing, implementation, data migration, ongoing support, and integration costs.

Deep-dive comparison

Pricing and total cost of ownership

The pricing models of these three DMS platforms reveal as much about their business strategy as their technology.

CDK Global negotiates pricing on a per-dealership basis, with costs heavily influenced by contract length, module count, and rooftop volume. Small single-point dealers on CDK's entry-level tiers report monthly costs around $2,000–$5,000. Mid-size groups (5–10 rooftops) typically pay $8,000–$15,000/month. Large groups and public retailers — many of whom were left without operational systems for weeks after the 2024 ransomware incident — pay $20,000–$30,000+/month for full-suite deployments across dozens of modules (DMS core, CRM, F&I, service, parts, reporting, digital retailing). Implementation fees for a mid-size group run $25,000–$75,000. Data migration from a competing DMS adds another $15,000–$40,000.

CDK's contracts traditionally run 3–5 years with auto-renewal clauses and significant early-termination penalties that can exceed $200,000 for large groups with time remaining on their term. Post-ransomware, this has become a major point of contention: dealer groups that previously accepted CDK's standard terms are now demanding shorter contracts, pricing concessions, and contractual commitments to infrastructure resilience and business continuity planning. CDK has responded by offering more flexible terms to large strategic accounts, but the default offering remains term-locked with substantial penalties for early exit.

One structural advantage CDK holds is module flexibility. Dealers can pick and choose which CDK modules they need — DMS core, CRM, F&I, service scheduling, parts management, reporting — and pay only for what they use. This unbundled approach means a dealer running a lean technology stack pays less than one running the full CDK suite, but it also creates the industry's most complex and opaque pricing structure, with module-level pricing, per-user fees, integration surcharges, and support tier costs that can vary wildly between similarly sized dealers.

Tekion charges a flat, all-inclusive SaaS subscription that covers DMS, CRM, F&I, service, parts, and reporting under one fee. No per-module pricing. No negotiating. Typical costs: $5,000–$15,000+/month depending on data storage requirements and rooftop count. One of Tekion's original selling points was month-to-month or annual contract flexibility — no 5-year lock-in, no auto-renewal traps. Implementation fees range from $30,000–$80,000+ for data migration and process configuration.

The flat-fee model is both Tekion's greatest pricing strength and a potential disadvantage. For a mid-size group paying $12,000/month for the entire Tekion stack, the cost is predictable and transparent — no surprise module fees creeping up at renewal. But for a small dealer who would only use a subset of DMS capabilities and pay $3,000–$4,000 on CDK, Tekion's minimum entry point of $5,000+ means they are paying for capabilities they may not need. The total cost over three years is often competitive with CDK and Reynolds, but the upfront migration cost ($30,000–$80,000+) and operational disruption during cutover have proven more painful than Tekion's sales process sometimes suggests. Early adopter reports from 2022–2023 documented significant data mapping errors and extended stabilization periods that drove total migration costs well above initial estimates.

Reynolds and Reynolds is the most expensive platform on a per-user basis and the least transparent about it. Pricing is not publicly disclosed. Industry estimates place Reynolds at $3,000–$15,000+/month depending on module mix. Reynolds historically charges premium pricing and enforces it through bundled product requirements — you cannot pick and choose modules the way you can with CDK. If you want ERA's accounting module, you are also buying ERA's CRM, ERA's F&I, and ERA's document management. This all-or-nothing approach drives up the effective cost for dealers who would prefer to use specialized third-party tools for CRM, F&I, or digital retailing.

Contract terms are the industry's longest, often 5–7 years, with aggressive early-termination penalties that Reynolds has a documented history of enforcing through legal action. Dealers who have tried to leave Reynolds mid-contract report legal threats, non-disparagement clauses, and data-access restrictions imposed during the transition period. Reynolds also charges dealer associations — franchise fees calculated as a percentage of DMS spend — meaning the total bill is higher than the platform cost alone suggests. For a mid-size group paying $10,000/month to Reynolds, the all-in cost including association fees, forced module bundles, and support contracts can exceed $15,000–$18,000/month when fully accounted.

Winner by price: CDK Global — for small to mid-size dealers who need only a subset of modules. Winner by transparent, predictable pricing: Tekion — flat-fee all-inclusive, no module games, no negotiating. Most expensive overall: Reynolds — by a wide margin when you account for forced bundles, association fees, and aggressive contract terms.

Cloud-native vs on-premise architecture

This is the most consequential technology decision a dealer can make in 2026. The legacy vendors are racing to modernize, but "cloud" means different things to different DMS providers, and the gap between marketing claims and architectural reality is wide.

CDK Global is the furthest along in its cloud migration among the legacy players, but that is a low bar. CDK Cloud (hosted/private cloud versions of legacy applications) and CDK Drive (a partially modernized, cloud-native UI layer) represent two different levels of cloud commitment — and neither constitutes genuine cloud-native architecture. CDK Cloud is essentially the old on-premise software running in CDK's data centers. It is better than maintaining a server in your back office, but it shares the same fundamental architecture: monolithic codebase, batch-processing-oriented data flows, and client-server design patterns that predate modern cloud computing.

CDK Drive is newer, with a browser-based interface, real-time data refresh in some modules, and a more modern UX. But CDK Drive does not replace the entire CDK stack. Many dealers run a hybrid environment — CDK Drive for front-end sales and service workflows, CDK Cloud or legacy applications for back-end accounting, parts, and reporting. This split creates data synchronization challenges, training complexity, and integration friction that a genuinely unified platform would not have.

The 2024 ransomware attack exposed the fragility of CDK's infrastructure in brutal detail. Backup and recovery processes were inadequate — dealers were down for up to two weeks. CDK's post-incident communication was heavily criticized as opaque and insufficient. The attack also revealed that CDK's architecture lacked the isolation and redundancy that modern cloud-native systems provide as standard features. Post-ransomware, CDK has accelerated infrastructure hardening, invested in multi-region redundancy, and improved disaster recovery capabilities, but the underlying architecture is still burdened by decades of technical debt and architectural decisions made in an era when on-premise servers were the only option.

Reynolds and Reynolds has been the most resistant to cloud architecture among the major DMS providers. The company's core ERA product was designed as an on-premise, server-based system with terminals at each user workstation — a design philosophy rooted in the 1990s. Reynolds ERA Ignite, launched as a cloud/evolutionary version, runs on modern infrastructure but shares much of ERA's architectural DNA: the same data models, the same workflow logic, the same integration patterns.

Many Reynolds dealers still run on-premise servers in their dealerships, physically maintained by Reynolds field service technicians who visit the dealership in person. Reynolds' cloud strategy has historically been to offer hosted versions of the same on-premise software rather than rebuild for the cloud. The company has invested in modernization since 2023–2024, and newer Reynolds installations are more likely to be hosted in Reynolds data centers, but the platform was not born in the cloud and the architecture shows it. Mobile experiences are poor or non-existent. API performance lags cloud-native competitors. Real-time data processing between modules is constrained by the underlying batch-oriented architecture. For a dealer evaluating architectural readiness for the next decade, Reynolds represents the most entrenched legacy position.

Tekion is the only platform on this list that was born in the cloud, built from scratch on AWS with a microservices architecture. There is no on-premise version, no legacy codebase to maintain, no "lift and shift" compromises. The UI is modern, mobile-first, and responsive — designed for a service advisor who walks the lot with an iPad, not a desk-bound administrator working on a terminal emulator. Real-time data flows between modules because they share a unified data layer and microservice mesh rather than being stitched together through point-to-point integrations. Updates are deployed continuously rather than quarterly or annually.

Tekion's AI-native design is also architecturally significant. The platform ingests and processes data in a unified data lake, which means AI features — automated deal scoring, service propensity modeling, inventory demand forecasting — are built into the platform's data layer rather than bolted on as separate products that require their own integrations. For a dealer who values modern architecture — automatic backups, zero-downtime maintenance, security patching, elastic scaling, mobile-first UX — Tekion's technology stack is objectively superior to both legacy competitors.

The trade-off: a cloud-native platform with a shorter track record has fewer battle-tested workflows. Edge cases only emerge through years of real-world usage across diverse dealer types — the odd OEM reporting requirement, the unique state regulation, the rare F&I product configuration — and Tekion simply has not been in production long enough to have encountered and resolved all of them. Dealers migrating to Tekion should expect to encounter workflow gaps that require workarounds, especially in their first year of operation.

Winner by architecture: Tekion — genuinely cloud-native, microservices-based, AI-native, modern from day one. Most legacy debt: Reynolds — the furthest from modern cloud architecture despite recent investments. Most improved post-breach: CDK — significant hardening investment, but still carrying decades of technical debt.

Integration ecosystems

Your DMS is the system of record for accounting, inventory, sales, service, and parts. How well it connects to the rest of your technology stack determines whether your dealership operates on clean, real-time data or manual re-entry and spreadsheets. The integration philosophies of these three vendors could not be more different.

CDK Global operates the industry's largest and deepest integration ecosystem — a consequence of 50+ years of market dominance and OEM certification relationships. CDK's APIs connect to virtually every major third-party vendor in automotive retail: CRM providers (Salesforce, Elead, HubSpot), inventory platforms (vAuto, MAX Digital, LotLinx), website providers (Dealer.com, Dealer Inspire, DealerOn), F&I providers, credit application processors, lenders, OEM data feeds, digital retailing tools, and service scheduling platforms.

The depth of these integrations varies. CDK's legacy APIs (CDK Data Pass, CDK Integration Cloud) are well-documented and battle-tested — they have been connecting dealer systems for decades. Newer platforms and emerging categories often require custom integration work through CDK's partner program, which can take 6–12 months for certification. The post-ransomware period also revealed a structural fragility: many CDK integrations broke during the outage because they depended on CDK-hosted middleware that went down with the core system. Re-establishing those integrations after recovery required manual reconnection and re-authentication across hundreds of vendor relationships, exposing the hidden cost of integration depth built on monolithic architecture.

For dealers considering CDK today, the integration breadth is a genuine competitive moat. No other DMS connects to as many OEM systems, as many third-party vendors, or as many specialized automotive tools. If your dealership runs a complex technology stack with multiple specialized vendors, CDK's integration network is likely the only way to make all of them work together without custom development.

Reynolds and Reynolds operates the most closed integration ecosystem of the major DMS providers. Reynolds historically required dealers to use Reynolds-owned products for CRM, F&I, document management, and accounting — and charged premium integration fees when dealers insisted on third-party alternatives. The walled-garden approach is softening: Reynolds now offers the Reynolds API platform and an official partner program. But the integration process remains more expensive, slower, and more restrictive than CDK's or Tekion's.

Dealers running Reynolds should expect higher costs for third-party integrations (integration fees of $500–$2,000/month per connected system are not uncommon), a limited set of pre-built connectors compared to CDK, slower certification timelines for new partners (often 12–18 months from vendor application to production-ready connector), and less flexibility to swap out components of the technology stack without touching the DMS core. The Reynolds partner ecosystem exists, but it is smaller and less mature than CDK's — a dealer running a specialized CRM or F&I tool may find that the connector they need simply does not exist.

For the Reynolds dealer who is fully committed to the Reynolds ecosystem — running Reynolds CRM, Reynolds F&I, Reynolds document management — the integration walled garden is largely invisible because the components are designed to work together. The friction only becomes apparent when the dealer wants to use a best-in-class third-party tool alongside the Reynolds DMS core.

Tekion was designed with open APIs from day one. The Tekion Marketplace offers pre-built connectors to major third-party tools, and the platform's API-first architecture means new integrations can be developed faster than on legacy platforms — often weeks rather than months. Tekion integrates with major CRMs (Salesforce, Elead, HubSpot), website platforms (Dealer.com, Dealer Inspire, DealerOn), inventory management tools (vAuto, MAX Digital), F&I providers, and service scheduling platforms.

The maturity of these integrations is the caveat. Some Tekion connectors are newer and less battle-tested than their CDK equivalents. Dealers migrating to Tekion should verify that their specific third-party tools have mature, production-tested connectors before committing. A connector that supports basic data exchange may not support the more complex, dealer-specific workflow configurations that years of iteration on a CDK or Reynolds integration would have ironed out. Tekion's open API architecture means that custom integration development is feasible, but it requires developer resources that most dealerships do not have in-house.

The most significant integration risk for Tekion is OEM certification depth. CDK's decades of OEM relationships mean CDK is certified for virtually every OEM data feed, reporting requirement, and incentive program. Tekion is building these certifications — and has made significant progress — but any OEM-specific data feed or reporting requirement that Tekion has not yet certified represents a gap that the dealer may need to work around.

Winner by integration breadth: CDK Global — most pre-built connectors to the widest range of vendors and deepest OEM certifications. Winner by architectural openness: Tekion — API-first design, faster connector development, modern integration paradigms. Most restrictive: Reynolds — improving slowly but still the hardest DMS to connect to non-owned products.

Migration difficulty

Switching DMS platforms is the single most disruptive technology project a dealership can undertake. The cost — in dollars, staff time, operational disruption, and data integrity risk — is consistently underestimated by dealers who have not experienced a DMS migration before. These three platforms present very different migration profiles.

Migrating from CDK is the second-hardest migration in the industry (behind Reynolds). CDK's data structures are complex but better documented than Reynolds, and CDK's API ecosystem makes partial data extraction more feasible. CDK offers data migration services to dealers leaving the platform, but dealers report that CDK-provided migration extracts tend to minimize the completeness of what the new DMS receives — the incentive structure is not aligned with a smooth departure.

The primary barrier to leaving CDK is the contract penalty. Early termination from a CDK agreement with 2+ years remaining can cost $50,000–$200,000 or more, depending on the size of the group and the remaining contract value. This is by design: the termination penalty creates a financial disincentive that keeps dealers on the platform even when they are dissatisfied. Post-ransomware, some dealers have successfully negotiated reduced termination fees, but CDK's standard contract still treats early exit as a revenue event.

Independent DMS migration firms typically charge $20,000–$50,000 for a CDK-to-competitor migration for a mid-size group, with the cost driven by data mapping complexity, the number of modules being migrated, and the number of third-party integrations that need reconnection. Timeline: 6–12 months from contract signing to stable operation on the new platform. The dual-running period — operating both systems in parallel during migration — is typically 2–4 months and places significant strain on dealership staff who must enter data in both systems.

The data migration itself carries risk. Historical accounting data, customer records with service history, parts inventory with bin locations, vehicle inventory with holdback and incentive data, F&I product records, and dealership-specific configuration settings — each of these data domains maps differently to each DMS, and edge cases inevitably arise where data does not transfer cleanly. Dealers should budget for 200–400 hours of manual data cleanup and reconciliation post-migration.

Migrating to or from Tekion carries a different set of risks than migrating from a legacy incumbent. The data migration from a legacy DMS to Tekion is moderately difficult. Tekion provides migration services and the cloud architecture simplifies data import — standardized schemas, API-based data loading, automated validation — but early adopter reports from 2022–2023 documented significant data mapping errors: VIN records lost in translation, customer duplicate records created during migration, accounting balances that did not tie out, and service history gaps. These issues required hours of manual cleanup post-go-live.

The platform's relative immaturity means fewer migration reference sites with similar dealer profiles. A CDK dealer with 15 years of accumulated data and complex OEM reporting requirements will find fewer reference dealers who have been through the exact same migration journey compared to, say, a CDK-to-DealerTrack migration. Tekion migrations typically take 3–9 months for single-point stores, extending to 12+ months for multi-rooftop groups.

The contractual cost of leaving Tekion is low — month-to-month terms mean no early-termination penalty. But the sunk cost of implementation ($30,000–$80,000+) and the disruption cost of another migration makes switching an expensive decision regardless. The most significant migration risk for Tekion is organizational: the platform requires dealership staff to learn an entirely new workflow paradigm, not just a new interface. Staff who have been using CDK or Reynolds for 10+ years will face a steeper learning curve than a migration from one legacy system to another would require.

Migrating from Reynolds is the hardest migration in the DMS industry — and it is not close. Reynolds' data schema is proprietary and poorly documented. Customer records, vehicle history, accounting data, service history, and parts inventory — all structured in ways that make extraction and mapping to another system exceptionally difficult. Data extraction typically requires Reynolds professional services (at Reynolds' pricing rates) or specialized third-party migration firms that charge a premium for Reynolds work.

Terminated Reynolds users report: difficulty accessing historical data after contract end, CSV exports that are incomplete or corrupted, and data structures that do not map cleanly to any competing platform. Some dealers report that Reynolds deactivated their access to historical data during the transition period, leaving them unable to reference customer service history or accounting records while the new system was being populated. This is not an accident — the data structure and access control are designed to make leaving painful enough that most dealers do not attempt it.

The Reynolds migration timeline is the industry's longest: typically 9–18 months from contract signing to stable operation. During this period, the dealer is paying both Reynolds and the new DMS — an expensive dual-running cost that can run $15,000–$30,000/month for a mid-size group. Legal risk is also a factor. Reynolds has a documented history of enforcing non-disparagement clauses (which prevent departing dealers from discussing their migration experience publicly), non-compete terms in service agreements, and seeking damages for early termination. The legal cost alone can exceed $25,000–$50,000 for a contested departure.

Independent migration specialists estimate Reynolds-to-Tekion or Reynolds-to-CDK migration costs at $50,000–$150,000 for a mid-size group, depending on the number of modules, the complexity of data structures, and the level of Reynolds cooperation (which varies). The most honest advice a migration consultant can give a Reynolds dealer: if you do not absolutely need to leave, do not.

Easiest platform to leave: Tekion — month-to-month terms, no contract penalty, cloud-native data export tools. Most difficult to leave: Reynolds — proprietary data structures, legal barriers, aggressive contract enforcement, and the longest migration timeline in the industry.

Customer support and account management

DMS support quality matters more than for most software categories. When the DMS goes down, the dealership cannot sell cars, close deals, process payoffs, or run payroll. The support experiences of these three vendors reflect their fundamentally different business models.

CDK Global had a mixed-to-poor support reputation before June 2024. After the ransomware attack — where dealer operations were frozen for up to two weeks, communication from CDK was opaque, and the recovery process was chaotic — dealer trust collapsed to historic lows. Multiple dealer groups publicly reported: inability to reach CDK support during the crisis, conflicting guidance from different CDK account representatives, reimbursement offers that covered a tiny fraction of actual business interruption losses, and inadequate business continuity planning that left dealers without operational systems or guidance on manual workaround procedures.

Post-ransomware, CDK has invested heavily in support infrastructure: expanded staffing levels, improved incident communication protocols, multi-region system redundancy, and enhanced disaster recovery capabilities. But the trust damage is generational. Many dealers who survived the 2024 outage are actively evaluating alternatives for the first time in decades, and CDK's renewal conversations are now significantly harder — dealers who used to sign without negotiation are now demanding contractual support SLAs, backup infrastructure commitments, and business continuity plans built into their agreements.

For day-to-day support outside of crisis scenarios, CDK offers the typical large-vendor experience: tier-1 phone/chat support for basic issues (average hold times of 15–45 minutes reported), dedicated account management for large groups, and a professional services arm for complex needs. Ticket resolution times vary widely by issue category, with integration and configuration issues typically taking longer than standard operational questions. The post-ransomware CDK is making genuine investments in support quality, but the cultural and operational scars from 2024 will take years to heal.

Tekion has the most polarized support profile in the DMS industry. A subset of dealers — particularly those who are technology-forward and willing to partner closely with Tekion through the learning curve — praise the responsiveness, product knowledge, and willingness to iterate based on dealer feedback. These dealers describe a startup-like support relationship where they have direct access to product managers, their feature requests are taken seriously, and platform improvements happen quickly based on real-world usage.

Another subset — particularly dealers who came from Reynolds or CDK with expectations of "it just works" stability — report frustration with bug resolution timelines, workaround requirements, and the sense that they are beta testers for a platform still under construction. 2024 and 2025 saw several high-profile dealer groups publicly step back from Tekion deployments, citing support quality and system reliability as contributing factors. The core tension is structural: Tekion's cloud-native architecture enables rapid iteration, but rapid iteration means changes that can introduce new issues and require ongoing adaptability from dealer staff.

Tekion has responded by expanding its customer success team, adding regional support directors, investing in self-service support tools with AI-assisted troubleshooting, and creating structured onboarding programs that aim to set clearer expectations about the post-go-live support experience. For dealers evaluating Tekion, the critical self-assessment question is: does your organization have the internal technical capability and organizational patience to work through early-stage platform challenges? If yes, Tekion's support model can be highly responsive and collaborative. If your dealership needs a system that requires minimal hands-on management and has mature, well-documented support processes for every scenario, the Tekion support experience may feel frustratingly incomplete.

Reynolds and Reynolds has a unique, bifurcated support dynamic. Dealers who are fully committed to the Reynolds ecosystem — running Reynolds CRM, Reynolds accounting, Reynolds F&I, and Reynolds document management — generally report strong support quality. Reynolds maintains a large field service organization with technicians who visit dealerships in person for hardware maintenance, system optimization, and staff training. For Reynolds-native operations, the in-person support model is genuinely differentiated from the phone-and-ticket model used by CDK and Tekion. A Reynolds field rep who visits your dealership monthly and knows your staff, your store layout, and your historical issues provides a level of localized support that no centralized help desk can match.

Dealers who use non-Reynolds products alongside Reynolds DMS report a very different experience. If you run Salesforce CRM with Reynolds DMS, or a third-party F&I platform, or a non-Reynolds service scheduling tool, the support experience deteriorates noticeably: slower response times, higher costs for non-standard service requests, less willingness to troubleshoot third-party integration issues, and a general attitude that problems arising from third-party connections are not Reynolds' responsibility even when they affect core DMS functionality.

The aggressive contract enforcement posture also colors the support experience. Dealers who are in dispute with Reynolds or planning to leave report a sharp deterioration in service quality — slower ticket resolution, reduced access to field support, and increased difficulty getting issues escalated. This is a feature, not a bug: the support experience is explicitly tied to the commercial relationship, and dealers who signal an intent to leave discover that the high-quality support they were receiving was conditional on their long-term commitment.

Winner by support in normal operations: Reynolds — for full-ecosystem dealers, the field support model is genuinely superior. Winner by architectural responsiveness: Tekion — cloud-native infrastructure and rapid iteration cycles provide faster issue resolution when the platform works as designed. Most damaged brand in support: CDK — post-ransomware trust recovery is a multi-year journey, but the investment in improvement is real and measurable.

Cloud architecture comparison table

Winner by dealer size

Single-point franchise dealer (1 store, 100–300 cars)

CDK Global is the strongest recommendation for a single-point dealer who values OEM integration depth and module flexibility. The ability to pay $2,000–$5,000/month for the specific modules you need — without paying for a full-suite platform you do not use — makes CDK the most accessible option at this scale. The integration ecosystem also matters more for single-point dealers who rely on a small set of third-party tools (website provider, CRM, F&I) and need them to work reliably with minimum complexity.

The risk is contract lock-in. A 3–5 year term with significant early-termination penalties is a heavy commitment for a single store. If the dealer grows, sells, or decides the platform is not working, exiting early is expensive. Post-ransomware, single-point CDK dealers should negotiate for shorter terms (1–2 years) and ask for contractual commitments on backup infrastructure and business continuity — the 2024 outage demonstrated that single-point dealers got the least attention from CDK's crisis response team.

If you are a single-point dealer who values modern technology and month-to-month flexibility: Tekion is worth evaluating despite the higher minimum pricing ($5,000+/month). The flat-fee all-inclusive model removes the risk of module creep pricing. Month-to-month terms eliminate the exit penalty. The cloud-native architecture provides automatic backups, mobile-first workflows, and modern UX. The gap is OEM certification depth — some single-point dealers have found that Tekion does not support their specific OEM's data feed or reporting requirements, creating manual workarounds that undermine the efficiency gains.

If you are a single-point dealer looking for the lowest possible cost: Neither Tekion ($5,000+ minimum) nor Reynolds ($3,000+ minimum, forced bundles) is the right choice at this scale. CDK with a focused module set is the most cost-effective option.

Multi-rooftop franchise group on CDK (3–10 stores)

CDK Global remains the pragmatic choice for groups already on CDK with substantial integration investments in place. The migration cost and operational disruption of moving 3–10 rooftops to a new DMS — $50,000–$150,000 in migration fees, 9+ months of dual-running and parallel operations, training across multiple stores — is rarely justified by the improvements any competing platform offers for a group that is currently functional.

The post-ransomware CDK is not the same company. Infrastructure has been hardened, cloud migration timelines accelerated, support staffing increased, and — most importantly — the commercial relationship has changed. Groups renewing with CDK in 2026 are in a stronger negotiating position than at any time in the last two decades. Use the leverage: demand shorter contract terms (2–3 years instead of 5), pricing concessions (10–20% reductions are achievable for mid-size groups), contractual support SLAs, backup infrastructure commitments, and a clear exit path with reasonable data export terms.

If you are on CDK and determined to leave: Tekion is the most compelling destination. The cloud-native architecture, AI capabilities, and all-inclusive pricing address the specific frustrations — architectural debt, module pricing opacity, technology stagnation — that drive CDK dissatisfaction. Budget for a 12–18 month migration window, $50,000–$100,000 in migration costs, and significant staff disruption during the dual-running period. The most successful CDK-to-Tekion migrations at this size have involved: (1) a dedicated internal project manager, (2) phased store-by-store go-live rather than a full cutover, (3) extended parallel running (3–4 months per store), and (4) explicit acceptance that year one will involve more workarounds and manual processes than the CDK baseline.

Multi-rooftop group on Reynolds (3–10 stores)

Your situation is fundamentally different from anyone else evaluating a DMS change. If you are on Reynolds and happy with the system — the stability, the field support, the integrated workflow — staying is the default correct answer. Reynolds' walled garden is frustrating if you want flexibility, but it is not operationally broken for dealers who have committed to the ecosystem. The migration cost ($50,000–$150,000+), timeline (12–18 months), and operational disruption are the highest in the industry, and the benefits need to be correspondingly substantial to justify the pain.

If you are on Reynolds and want to leave: Tekion is the most viable alternative for mid-size groups. The Reynolds-to-Tekion migration is difficult but less painful than Reynolds-to-CDK, which would involve migrating complex data structures from one legacy system to another — essentially paying twice for migration with no architectural upgrade. Tekion's month-to-month terms also offer a genuine escape from Reynolds' 5–7 year contracts and forced module bundling. Do not underestimate the migration cost and timeline. And verify that all your critical third-party tools have mature Tekion connectors before committing — a Reynolds dealer who is also running a non-Reynolds CRM or inventory platform should confirm the connector exists and is production-tested.

DealerTrack (Cox) is a secondary option for Reynolds dealers who want out but cannot afford Tekion's migration costs or risk profile. DealerTrack offers an easier migration path (less data complexity, standardized schemas), lower pricing, and month-to-month terms. The trade-off is that DealerTrack's feature depth at this dealer size may not match Tekion's comprehensive platform, and the Cox ecosystem alignment is a consideration for dealers who use non-Cox third-party tools.

The most important question for any Reynolds dealer considering a migration: Can your business absorb 12–18 months of operational disruption, $75,000–$150,000 in direct migration costs, and the risk of data integrity issues during the transition? If the answer is no — and for most 3–10 store groups it is — staying on Reynolds and negotiating the best renewal terms you can get is the financially rational decision, however emotionally unsatisfying that may be.

Large dealer group with corporate IT (10+ rooftops)

CDK Global is still the dominant choice among large groups and public retailers — not because it is the best technology, but because the OEM integration network, module breadth, and industry relationships are unmatched. CDK has integrations and certifications that would take years for a competitor to replicate. The 2024 ransomware attack did not change this math for the largest groups; it changed the relationship. Large groups who previously accepted CDK's contract terms and pricing are now negotiating aggressively — shorter terms, lower pricing, stronger SLAs, backup infrastructure requirements written into contracts. A large group renewing with CDK in 2026 should be getting a better deal than a large group renewing in 2023.

For large groups with 10+ rooftops, the integration depth argument is particularly strong. A large group running CDK has certified data feeds from every major OEM they represent, pre-built integrations with their CRM and inventory providers, and established workflows for corporate reporting and accounting consolidation. Rebuilding this integration ecosystem on a new DMS would cost $250,000–$500,000+ and take 18–36 months. The math is simple: unless the current system is operationally broken or the contract renewal terms are unacceptable, the migration cost exceeds the benefits.

Tekion is the most interesting alternative for large groups with the organizational maturity to manage a cloud migration at scale. A 15-rooftop group running Tekion has a unified, real-time data platform that CDK's legacy architecture cannot match. AI-native workflows — automated deal scoring, service propensity modeling, inventory demand forecasting — are built into the platform rather than bolted on as separate products requiring their own integrations and data feeds.

The risk is execution. Tekion has fewer large-group reference sites than CDK, and early large-group migrations experienced data integrity issues and extended stabilization periods that ran 3–6 months longer than projected. If you are a large group with strong IT leadership, an experienced project management team, and a tolerance for platform maturation, Tekion is worth a serious evaluation of 1–3 stores as a controlled pilot. If your group lacks deep technical resources and needs the system to work with minimal IT oversight from day one, CDK is the safer choice even with its architectural limitations.

For large groups that want to diversify DMS risk: Running different DMS platforms across different stores (CDK in the majority, Tekion in 1–3 pilot stores) is becoming more common among the largest groups. This approach avoids single-vendor lock-in, creates competitive tension between DMS vendors on renewals, and provides operational redundancy in case of another industry-wide DMS outage. The operational complexity of running multiple DMS platforms (separate training, separate integrations, separate support relationships) is real but manageable for groups with a corporate IT function.

Technology-forward group (values AI, modern UX, architecture)

Tekion is the clear choice for dealers who prioritize modern architecture above all other considerations. It is the only platform in this comparison that was born in the cloud, built on a microservices architecture, designed with an AI-native data layer, and delivered through a mobile-first user interface. For a dealer group that sees technology as a competitive differentiator — not just an operational utility — Tekion's architecture provides capabilities that CDK and Reynolds simply cannot match: real-time unified data across all departments, AI workflows embedded in the platform rather than bolted on, continuous deployment without maintenance windows, and an API-first design that makes custom integration development feasible.

The trade-off is operational maturity. Tekion's architecture is superior, but the platform has been in production at scale for fewer years. Workflow gaps exist. Some features that legacy DMS users take for granted — specific OEM report formats, industry-standard accounting practices encoded in the platform, certain parts and service subprocesses — may not work exactly as expected. The willingness to work through these gaps is the defining characteristic of a successful Tekion adopter.

If you are a technology-forward group who values architecture but needs more operational maturity: CDK Drive with a shorter contract term and aggressive pricing can provide a partial modernization path without the full risk of a platform migration. CDK Drive's browser-based interface and modernized UX are improvements over the legacy CDK experience, though it inherits the same underlying data architecture and integration patterns.

Budget-constrained dealer — any size

CDK Global is the most practical option for budget-constrained dealers when module flexibility is needed. The ability to start with a basic DMS core at $2,000–$3,000/month and add modules over time as the business grows provides a cost-efficient entry point. The 3–5 year contract term is a risk, but for a dealer who does not expect to change platforms in that timeframe, CDK's pricing at the low end is the most accessible of the three platforms evaluated here.

Tekion does not serve this segment well at its current pricing floor of $5,000+/month. The flat-fee all-inclusive model provides value for mid-size and large groups, but a single-point dealer paying $5,000+ for capabilities they will not use is not getting the best value for their budget.

Reynolds is not a budget-constrained option at any scale — forced module bundling, association fees, and premium pricing make it the most expensive option for this segment.

Summary decision matrix

The bottom line

The DMS platform decision is the most consequential technology choice a dealership makes. Get it right and your stores operate on clean, real-time data with integrations that just work. Get it wrong and you are locked into a multi-year contract with a system your staff resents, integration costs that grow every year, and a migration bill in the hundreds of thousands if you decide to leave.

CDK Global remains the default for large groups and the most practical option for small dealers because the integration network and OEM certifications act as barriers to entry that no competitor has fully matched. The 2024 ransomware attack permanently changed the relationship — dealers who used to renew automatically are now negotiating — but it did not change the practical reality that most dealers on CDK have no viable short-term path to leave without incurring significant cost and disruption. If you are CDK and staying, negotiate hard on your renewal: shorter terms, backup infrastructure requirements, pricing concessions of 10–20%, and contractual support SLAs. The post-breach CDK knows the leverage has shifted, and large groups especially should not sign standard terms without demanding changes.

Reynolds and Reynolds is the platform dealers love to hate and hate to leave. For the installed base that is fully committed to the ecosystem — running Reynolds across DMS, CRM, F&I, and document management — the field support model and operational stability provide genuine value that the industry's critics underappreciate. For anyone who wants flexibility, modern architecture, an open integration ecosystem, or an easier exit path, Reynolds is the wrong choice. The migration cost, timeline, and legal risk make leaving Reynolds the most expensive DMS decision a dealer can make. If you are a Reynolds dealer considering a change, treat the migration budget and timeline as your binding constraints — everything else flows from whether you can afford and manage the transition.

Tekion has the best technology architecture in the DMS industry and the least mature operational track record. For dealers who value cloud-native design, AI capabilities, open APIs, and month-to-month contract flexibility — and who have the organizational patience and technical capability to work through platform immaturity — Tekion is the most compelling long-term bet in the DMS space. For dealers who need a system that works reliably today with minimal hands-on management and maximum integration breadth, Tekion is still a risk that should be approached through a controlled pilot rather than a full-scale deployment. The most successful Tekion adopters are groups with dedicated IT leadership who treat the migration as a strategic transformation project, not a software replacement.
