What we provide today: a VIN history report (title brands, odometer readings, theft and salvage records, and auction records in Premium, where available) plus this free checklist. We don't authenticate vehicles or certify provenance.
1. Ownership chain
A continuous, explainable chain of ownership is one of the strongest signals of a well-documented car. Gaps aren't automatically a problem, but they should have a story.
- Compare the seller's name with the current title and registration.
- Ask for prior titles, bills of sale and registration records, and line up the dates.
- Check the history report for title transfers by state, title brands and odometer readings, and look for anything that conflicts with the seller's account.
- Note any periods of export, import or long-term storage, and ask for supporting paperwork.
2. Documentation
- Original window sticker, order form, build sheet or invoice, where they exist.
- Service and maintenance records, ideally with dates, mileage and the shop's name.
- Restoration records: invoices, photo documentation and parts receipts.
- Factory or manufacturer heritage certificates, where the manufacturer offers them.
- Owner's manuals, tool kits, keys and accessories that came with the car.
- Show, concours or club judging sheets, if the car has been judged.
3. Matching numbers
"Numbers matching" generally means major components (often the engine, and sometimes the transmission, rear axle and other parts) still carry the numbers or date codes that correspond to the car's original build. What counts, and where numbers are stamped, varies widely by make and model.
- Confirm the VIN or chassis number on the title matches the plates and stampings on the car.
- Have a marque specialist check engine and component stampings and date codes against build records.
- Look for signs of re-stamping, replaced VIN plates or altered tags.
- Treat "numbers matching" claims as something to verify, not take on trust.
4. Red flags worth a second look
- Title brands (salvage, rebuilt, flood) on a car presented as original or concours-level.
- Odometer readings that go backward, or very low claimed mileage without records to back it up.
- Paperwork that only starts after a major restoration.
- A seller who won't allow an independent inspection.
Where a history report fits
A VIN history report covers the reported record: title brands, odometer readings, theft and salvage records, and more, from commercial vehicle-history data sources. It works for vehicles with a standard 17-character VIN (generally 1981 model year and newer). It can't see private sales that were never reported, and it doesn't replace documentation or an inspection. Pre-1981 chassis-number support is coming soon.
