How big is the car clocking problem in the UK?
Car clocking, or odometer fraud, remains one of the most widespread forms of used car fraud in the UK. According to industry data, approximately 2.1% of used cars changing hands each quarter have had their mileage deliberately falsified. Scaled across the UK's used car market, that translates to an estimated 160,000 vehicles sold with fraudulent mileage every single year.
The financial consequences are serious. Research suggests that buyers of clocked cars overpay by an average of 48.8% compared to what the vehicle is actually worth. A car advertised as having covered 40,000 miles but which has actually done 90,000 miles is a fundamentally different purchase: tyres, brakes, clutch, and engine components will all be in far worse condition than the odometer suggests.
The UK's most clocked cars in 2025
The table below shows the models most frequently identified with odometer fraud in the UK, based on vehicle history check data. The percentage column shows the share of each model checked that displayed a mileage discrepancy. The average rollback column shows how many miles were typically removed from the clock.

| 1 | Nissan Qashqai | 9.7% | 15,490 | Very High |
| 2 | Volvo XC60 | 8.4% | 18,317 | Very High |
| 3 | Volvo XC90 | 7.2% | 22,400 | Very High |
| 4 | Land Rover Defender | 3.0% | 59,201 | Very High |

Why are SUVs and premium models targeted the most?
The logic behind which cars get clocked is straightforward: fraudsters target models where the financial reward is greatest and the fraud is hardest to spot without the right tools. A high-mileage Nissan Qashqai or Land Rover Defender can be worth several thousand pounds more than a lower-mileage equivalent, which makes rolling back the clock a lucrative proposition for unscrupulous sellers.
Premium German models from Audi, BMW, and Mercedes-Benz appear consistently in the top ten because their second-hand values are closely tied to mileage. A BMW 5 Series with 60,000 miles on the clock can command a considerably higher price than one that has covered 100,000 miles, giving fraudsters a strong incentive. The Nissan Qashqai's dominance at the top of the list is partly a volume effect: it has been one of the UK's best-selling SUVs for years, meaning there are simply more of them in circulation and more opportunities for fraud in a fast-moving second-hand market.
Nearly new cars are not immune
A common misconception is that car clocking only affects older, high-mileage vehicles. The data tells a different story. Among cars under five years old where mileage fraud was detected, the average rollback exceeded 20,000 miles. KIA models showed mileage discrepancies in nearly 9% of checks on nearly-new vehicles, with Nissan close behind at 6.84% and Dacia at 6.16%.
One reason newer cars are targeted is that many are bought with PCP or HP finance agreements that include strict annual mileage limits. When drivers exceed those limits, they face significant penalties at the end of the agreement. Some use mileage correction services to avoid those charges before returning the car, which then enters the used market with a dishonest history. The buyer down the line has no idea the car has been driven considerably harder than the odometer suggests.
Electric vehicles are not safe either
As more electric vehicles enter the used car market, they too have become targets. Around 2.6% of used EVs checked in the UK have shown signs of mileage manipulation. This is particularly concerning because battery health is directly linked to usage, and a clocked EV may have a battery in significantly worse condition than the mileage figure implies.
How to spot a clocked car before you buy
The most reliable protection is a full vehicle history check, which cross-references MOT mileage records, service history entries, and national databases to build a complete picture of how the mileage has changed over time. Any unexplained drops or implausibly static readings over a period of several years are major red flags.
Physical checks can also help. Look at the condition of the driver's seat bolster, steering wheel, gear knob, and pedal rubbers. If a car is advertised with 25,000 miles but the steering wheel leather is worn smooth, something does not add up. Ask to see all service history documents and check that the recorded mileages in those documents tell a consistent story from one service to the next.
What happens if you buy a clocked car?
If you unknowingly purchase a clocked car, you are in a difficult position. You will have overpaid for a vehicle that is more worn than you believed, and you may face unexpected repair costs sooner than anticipated. When you come to sell the car, any prospective buyer who runs a history check will see the mileage discrepancy flagged, which will significantly reduce the car's value and make it harder to sell.
Legally, if you can demonstrate you bought the car in good faith and were not informed of the discrepancy, you may have a claim against the seller under the Consumer Rights Act 2015 or the Fraud Act 2006. Reporting the matter to Trading Standards is advisable. However, the most practical course of action is prevention: a vehicle history check before purchase costs a fraction of what a clocked car can end up costing you.
Frequently asked questions about car clocking
What is car clocking?
Car clocking, also known as odometer fraud, is when a vehicle's mileage reading is deliberately wound back to make the car appear to have covered fewer miles than it actually has. This is done to inflate the car's resale value or to hide excessive wear and tear. Whilst altering your own car's mileage is not illegal in the UK, selling a car with a falsified odometer without disclosing it to the buyer is a criminal offence under the Fraud Act 2006.
Which cars are most commonly clocked in the UK?
According to 2025 data, the Nissan Qashqai is the UK's most clocked car, with nearly 10% of checked vehicles showing mileage discrepancies. The Volvo XC60, Volvo XC90, Toyota RAV4, and Land Rover Defender also feature prominently. Premium German models including the Audi A6, BMW 5 Series, and Mercedes-Benz E-Class consistently appear in top-ten lists due to their high resale values.
How many miles are typically rolled back on a clocked car?
The average mileage rollback varies significantly by model. In 2025, the Land Rover Defender had the highest average rollback at 59,201 miles, followed by the Vauxhall Insignia at 40,896 miles and the Mercedes-Benz S-Class at 40,742 miles. Even smaller rollbacks of 15,000 to 20,000 miles can inflate a car's value by thousands of pounds and mask serious mechanical wear.
How can I tell if a car has been clocked?
The most reliable way to detect mileage fraud is to run a vehicle history check, which cross-references MOT records, service history, and database records to flag any inconsistencies in the mileage timeline. Physical signs can also help: look for unusual wear on the steering wheel, gear knob, driver's seat bolster, and pedal rubbers that does not match the stated mileage. Gaps or inconsistencies in the service history are another red flag worth investigating.
Is buying a clocked car illegal?
Buying a clocked car in good faith is not illegal for the buyer. However, knowingly selling a car with a falsified odometer without disclosure is a criminal offence. If you unknowingly purchase a clocked car, you may have grounds to pursue the seller under consumer protection legislation. Running a car history check before purchase is the most effective way to protect yourself from this type of fraud.
