How to spot a clocked car — mileage fraud checks that work

The best way to spot a clocked car is to compare the mileage on the dashboard with the mileage at every past MOT test. The free GOV.UK MOT history service shows these readings, so a drop or a strange jump is easy to see. Then check that service stamps, invoices and the wear on the car agree with the number on the clock.

A clocked car has had its odometer wound back to show fewer miles than it has really covered. This makes the car look newer and more valuable than it is. Always check before you pay.

How can I tell if a car has been clocked?

No single check is enough. Use several, and look for a story that fits together.

1. Check the MOT history. Look at the mileage at each test. Mileage should rise each year. A fall, or a long period with no rise, is a warning sign.
2. Compare the service book. Look at the stamps and the mileage written in. Ask for invoices that match.
3. Check the car's wear. Does the interior match the mileage? (See the wear section below.)
4. Run a paid history check. These can cross-check mileage against other records, not only MOT tests.
5. Ask the seller. Ask how long they have owned the car and how many miles they drive each year. Vague answers are a warning sign.

If two or more of these do not agree, walk away or ask for a discount that reflects the risk. Do not accept "the clock must have been wrong" as an answer.

Can I check a car's mileage for free?

Yes. The free MOT history on GOV.UK records the odometer reading at every MOT test since 2005 for cars in England, Scotland and Wales. You only need the registration number. Motofly also shows the DVSA MOT history on every listing, so you can check before you contact the seller. Our guide to reading MOT history explains each part of the record.

What to look for in the free record:

• A mileage drop between two tests.
• A flat period. For example, the same mileage across two years.
• A sudden jump after a low run, which can suggest a reading was mis-entered.
• Odd round numbers, or readings in kilometres on an imported car.
• Large gaps in the test dates.

A mis-typed reading at an MOT station does happen. One odd entry is not proof of fraud, but it needs an explanation from the seller.

Which records should match the mileage?

Collect as much paper evidence as you can and compare the numbers side by side.

Be careful with a service book. Stamps and entries can be faked, and blank books are sold online. An invoice from a real garage with a phone number you can call is stronger evidence. You can ring the garage and ask them to confirm the work and the mileage. Read how the V5C works to check the keeper history.

What wear signs give away high mileage?

Wear is hard to hide. Compare the car's condition with the number on the clock.

• Driver's seat. Look for a sagging cushion, torn side bolsters and shiny fabric.
• Steering wheel. A worn, shiny or peeling rim suggests heavy use.
• Pedals. Rubber covers worn smooth, or new pedal covers on an old car, are suspicious.
• Gear knob and gear lever. Worn paint or leather points to many gear changes.
• Key and key fob. A badly scratched, faded key on a "low mileage" car is odd.
• Door handles and switches. Look for worn lettering on buttons.
• Front end. Many small stone chips on the bonnet and bumper suggest a lot of motorway miles.
• Tyres and brakes. Very worn brake discs or mismatched tyres on a car with low miles need an explanation.
• Engine bay and underneath. Heavy dirt, leaks or rust on a car claiming a low reading.

Also look at the dashboard itself. Loose trim, scratches around the instrument cluster, or a digital display that flickers can mean someone has worked on it. Be careful with any car where the warning lights behave oddly when you turn the key.

Is selling a clocked car illegal?

It depends on whether the seller tells you. It is not illegal to offer a mileage-correction service, for example to fix a broken instrument cluster. But selling a clocked car without telling the buyer is not allowed. A trader who gives a false or misleading mileage can be prosecuted by Trading Standards under consumer protection law (the Digital Markets, Competition and Consumers Act 2024, which replaced the 2008 regulations in April 2025). Any seller, private or trade, who knowingly gives a false mileage to make money may also commit fraud under the Fraud Act 2006.

If you buy a car and later find it was clocked, you may have a claim. Private sales offer fewer protections than dealer sales, because a private seller must only describe the car honestly and the car must match that description. Our guide to private seller vs dealer explains the difference. Keep the advert, messages and receipts. If you think you have been the victim of fraud, contact Citizens Advice and Trading Standards. Check GOV.UK for the current process.

What should I do before paying?

Do not rely on one check. Follow this order:

1. Run the free MOT history before you travel to see the car.
2. Ask the seller for the service book and invoices.
3. Inspect the interior and engine bay in daylight.
4. Pay for a full vehicle history check. See HPI check vs MOT history for what each one covers.
5. Walk away if the story does not fit. There are many other cars on Motofly.

Frequently asked questions

Is my car clocked?

Check the MOT history for your registration number on GOV.UK. If the readings rise steadily with no drops, it is unlikely to be clocked. If you bought the car recently and see a drop, speak to the seller and keep your records.

Can a clocked car pass an MOT?

Yes. The MOT tester records the reading from the odometer but cannot prove it is correct. The MOT system warns the tester if the reading is lower than, or the same as, the previous test, but the car is not failed for it. The test is about safety and emissions, not about proving the mileage. That is why the history of past readings matters.

Does a low mileage always mean a clocked car?

No. Some cars really do cover few miles, for example a second car used for short trips. But very low mileage with heavy wear is a warning sign. Look for matching evidence such as dated invoices and regular MOT readings.

Does a full history check always find clocking?

No. A paid check can flag a mileage mismatch, but it only knows about recorded readings. If the odometer was altered before any record was made, it may not show. Use the check together with wear, paperwork and a careful inspection.

Is a car with a mileage drop always clocked?

Not always. A typing error at the MOT station or a replaced instrument cluster can cause a drop. Ask the seller to explain it and ask for proof, such as an invoice for a new cluster. If they cannot explain it, treat it as a red flag.
