Before you buy
A short checklist for buying a used car in the UK. We check what can be checked against official records; the rest is up to you in person.
What this site verifies
- · DVLA vehicle record: make, model, colour, fuel, engine size and first registration, matched to the registration plate.
- · MOT history: pass and fail results, recorded mileage at each test and advisory notes, shown on the provenance timeline above.
- · Field-level provenance: every fact on this page is labelled with its source. Anything we could not confirm is left empty, not filled in.
What you still need to check
- Outstanding finance, theft and write-off status. Run a vehicle history check (often called an HPI-style check) before paying. A car with finance owing can be repossessed from you.
- V5C logbook. Ask to see the original V5C. The name and address on it should match the seller and the place you are buying from, and the VIN on the V5C should match the car.
- Mileage consistency. Compare the odometer with the MOT history and service records. A reading lower than an earlier MOT is a warning sign.
- Test drive and inspection. Drive the car from cold on varied roads. Check that it comes with two keys and no warning lights, and consider an independent inspection.
- Written receipt. Get a dated receipt with the price, registration, VIN, mileage, and the names and addresses of both parties. Avoid cash where you can.
