We looked at switching from CDK to Tekion last year. Spent four months evaluating it. The product is genuinely better in a lot of ways but the migration risk and the staff retraining cost killed the project. Ended up renegotiating our CDK contract instead and got maybe 8% off after threatening to leave. That's the game. They know you're not leaving. You know you're not leaving. Everyone pretends the threat is real and you get a modest discount. Rinse and repeat every renewal cycle.

We switched from one of the big two to Tekion three years ago. It was brutal for 6 months. Now we'd never go back. The transition cost is real but so is the ongoing cost of staying on legacy systems with annual price increases you can't negotiate. At some point the math tips.

We moved from Reynolds to Tekion eighteen months ago and I would not recommend it to anyone who is not prepared for a genuinely disruptive twelve month transition. The decision was right for us long term because Reynolds had raised our contract rate three times in four years with no meaningful product improvement and the data hostage dynamic was getting worse. What nobody tells you going in is that Tekion's OEM integration completeness varies significantly by brand and some of the integrations that are listed as available are available in the sense that they technically exist, not in the sense that they work reliably. We had a four month period where our service lane warranty claim submission required a manual workaround because the integration was broken and Tekion's support timeline was measured in weeks not days. We are past that now and the platform is genuinely better. But the switching cost is not just money. It is six months of operational degradation you have to be willing to absorb.

It’s basically Stockholm syndrome. We pay more every year for the same broken systems.

The switching costs are terrifying, but staying with these legacy vendors feels even worse.

From the vendor side the consolidation is actually clarifying rather than paralyzing if you reframe how you think about it. The stores most locked in to a specific DMS are also the ones most willing to pay for a vendor who has built a genuinely deep integration with that platform rather than a shallow connection across five of them. I have closed more deals in the last year leading with our CDK depth specifically than I ever did leading with the breadth of our integrations. Dealers who feel captive to their DMS are essentially pre-qualified to value a vendor who meets them where they are rather than asking them to change their infrastructure. The play is not to compete on flexibility. The play is to be the deepest possible option on the two or three platforms that own the market and charge accordingly.

From the vendor side the consolidation is creating an unexpected opportunity for the handful of players who saw this coming. When dealers feel trapped with their DMS they become significantly more willing to pay for best-in-class point solutions that work on top of whatever system they are stuck with rather than replacing it. The integration layer is where the money is moving. Vendors who built flexible API connections to CDK and Reynolds two years ago when it was expensive and painful are now getting premium pricing because dealers need solutions that do not require a DMS switch they cannot afford operationally or financially. The vendors who built only for one platform or who required a DMS change as a prerequisite are having a very different 2026. Platform consolidation accelerated the market for interoperability. That is not the obvious read but it is what the deal flow is showing.

The "Stockholm syndrome" comment is spot on. We’re stuck paying legacy prices for outdated tech because the operational risk of switching is just too high. Until there’s a universal data standard, we’re basically just ATM machines for CDK and Reynolds. It's an incredibly frustrating and exhausting cycle.

We are actually mid-migration right now, 14 months in, and I want to share something nobody told us going in. The switching cost is not primarily financial and it is not primarily technical. It is the loss of informal workarounds your staff built over years to compensate for the limitations of the old system. Those workarounds are invisible until they disappear and your team is suddenly trying to do things the new system does correctly but differently from how they learned to do them. Three of our best service advisors nearly quit in month four because their daily rhythm was completely disrupted. We got through it and the new system is genuinely better. But anyone treating a DMS switch as primarily a technology or pricing decision is going to be blindsided by the human change management problem that is actually the hardest part.

Reply 9 is spot on—it’s the "informal workarounds" that make switching a nightmare. You don't realize how much your workflow relies on duct-taping broken systems until you try to fix them. We’re staying put for 2026; the operational risk of retraining everyone is just too high right now.

The OEM integration layer the OP mentions is worth examining separately from the DMS captivity question because it is creating a dynamic that neither dealers nor vendors are fully tracking yet. As OEMs push their own data platforms on top of existing DMS infrastructure, they are essentially building a second layer of lock-in that is separate from the DMS relationship entirely. A dealer can theoretically switch from Reynolds to Tekion but they cannot easily switch away from an OEM-mandated data integration that is tied to certification status or incentive eligibility. That second layer is where the real captivity is heading. The vendors who understand this are building toward the OEM data layer rather than competing purely on DMS integration depth. The dealers who understand it are asking harder questions about what data flows where before they agree to any new OEM-sponsored technology requirement.

The point about "informal workarounds" is spot on. We’ve spent years learning how to duct-tape legacy systems together, and losing that muscle memory is a massive barrier to switching. It’s not just the financial cost; it’s the operational chaos that keeps us chained to these legacy platforms.

Tekion is the only one actually winning net new logos at scale right now and even their deals are taking longer to close than they were two years ago because dealers have been burned enough times to slow down. The vendors that are navigating this best are the ones who stopped trying to replace the DMS and started building on top of it. If you can integrate cleanly with all three major platforms and show value without requiring a migration conversation you have a real opening. The groups moving DMS in 2026 are almost exclusively the ones getting acquired and having a platform forced on them. For everyone else, the switching cost math just doesn't work. Build for the locked-in reality rather than waiting for liberation.

The play for vendors in this environment is to build integrations that are DMS-agnostic wherever possible and lead with that explicitly in sales conversations. Dealers who feel locked in are actually more receptive to vendor products that reduce their dependency on any single platform, not more resistant. The ones making moves in 2026 are mostly Tekion conversions at stores that came up for contract renewal and had a principal willing to absorb the pain. The switching cost argument is real but it is not permanent captivity. It is captivity until the contract expires and someone at the ownership level gets angry enough. Vendors who position around that moment have an opening.

The "Stockholm syndrome" comment really resonates. We keep paying more for legacy tech because the operational risk of switching is just too high. Reply 9’s point about losing those "informal workarounds" is the biggest hurdle no one talks about during the initial sales pitch. Truly a nightmare.
