Why buying teams keep it pinned
It turns every appraisal into a fast, repeatable process · fewer surprises, better buys, tighter margins.
Appraise at auction speed
No copying details into another tab. Click once and the checklist is ready before the next lot rolls through.
Protect your margin

Every check on record
Saved straight to your VehicleFaults account, so your whole buying team works from one searchable history.
Detects the vehicle for you
On a supported listing, a Check faults button appears. It reads the VIN, make, model, year and mileage straight off the page.
Instant fault checklist
Get a grounded, model-specific inspection checklist in seconds — the same engine that powers vehiclefaults.com.
