Quick Answer
To check a car's mileage is genuine, compare the odometer reading against the mileage recorded at every MOT — it should rise steadily with no drops or impossible jumps. Then check the physical wear (pedals, steering wheel, seats) matches the claimed mileage. A history check flags anomalies automatically.
Compare the MOT mileage trail
Every MOT since 2005 records the mileage. List the readings in date order — genuine mileage climbs steadily. A figure that decreases, stalls for years then jumps, or shows an impossible annual leap is the clearest evidence of clocking.
Check the physical wear matches
- Worn pedal rubbers on a supposedly low-mileage car
- A shiny or worn steering wheel and gear knob
- Sagging, worn or heavily bolstered driver's seat
- Stone chips and wear inconsistent with the claimed mileage
Let a check do the maths
A vehicle history check pulls the full mileage record and automatically flags discrepancies against a national mileage database, so you don't have to spot every jump yourself.

Check for mileage discrepanciesFrequently Asked Questions
Is clocking illegal?
Adjusting an odometer isn't itself illegal, but selling a clocked car without disclosing it is fraud under consumer protection law. Either way it's a serious red flag.
How common is car clocking?
More common than many buyers think, driven by mileage-based finance and leasing. That's why checking the MOT mileage trail is one of the most valuable pre-purchase steps.
