Build a dated mileage timeline
Put inspections, registrations, service invoices, listings, and sale records in date order. A later lower reading, a long unexplained gap, or implausibly low annual use deserves an explanation in writing. CARFAX may add dated readings when it returns mileage history for that VIN.
What “no mileage records” means
If CARFAX does not return odometer events, VinSentry will not invent a clean mileage story. That gap is common on private sales and on cars outside CARFAX’s US and Canadian coverage. It is not proof the odometer was never altered.
Physical clues still matter
Compare stated mileage with pedal, seat, steering-wheel, tire, and switch wear. Digital clusters can be changed. Where a workshop can read control-module mileage, treat that as another data point, not as courtroom proof on its own.
Protect the purchase
Ask the seller to explain conflicts in writing and keep copies of ads. Check how mileage is described on the title. Enter the VIN here to see whether CARFAX returned a mileage history after purchase — then inspect the car anyway.
