Why dealers trust LotSignal
Every design decision comes from one principle: an acquisition verdict is only useful if a human buyer can defend it. That means no substituted comps, no hidden math, and no silent overwrites.
Exact-trim, or nothing
A 3500HD is never compared to a 1500. A hybrid is never compared to gas. If exact-trim comps aren't there, LotSignal says 'insufficient' — it doesn't fake a score.
The math is visible
Every verdict shows retail low/median/high, recon cost, target gross, and the exact comps used. Your buyer can defend the offer on the phone with the seller.
Original appraisal is preserved
Every save creates an immutable snapshot. Re-checks add new snapshots — they never overwrite what your team saw when they saved it.
Dealership-scoped, multi-user
Buyers save from the extension. Managers triage in the portal. Roles (admin/manager/buyer) and tenancy are enforced by row-level policies, not client code.
Data provenance
Comps come from MarketCheck, a professional automotive data provider. Every appraisal records the run ID and extension version.
No vendor lock-in
Your Watchlist and appraisal history are exportable. This is a tool for your buyers, not a walled garden.
