How to spot a clocked car (mileage fraud)
By Plateworthy · Updated · Editorial policy
'Clocking' means rolling back a car's odometer to make it look like it has done fewer miles, so it sells for more. It's more common than people think, and a lower reading can hide heavy wear. Here's how to catch it.
Why mileage is checkable for free
Every MOT records the odometer reading. Because those readings are public, you can plot a car's mileage over time, and usable readings can be compared over time, while allowing for unit changes, entry errors or a replacement odometer.
A later reading that's lower than an earlier one, or an implausible jump, is a red flag. Our free check computes this mileage-anomaly flag for you automatically.
Physical signs to look for
Compare the mileage with the car's condition: a worn steering wheel, shiny pedals or a sagging driver's seat on a 'low-mileage' car don't add up.
Check service stamps and old MOT certificates for mileages that match the digital history.
Common questions
- Is clocking illegal?
- A misleading mileage claim can raise serious consumer and fraud issues. A corrected entry or replacement instrument cluster can also explain a discrepancy. Ask for evidence, preserve the advert and seek independent consumer advice if a seller misrepresented the mileage.
- Can mileage be checked for free?
- Yes. The MOT history is free, and our free check plots the mileage and flags any reading that goes backwards or jumps implausibly.
