How Mileage Discrepancies Affect MOT History and Resale Value

When buying or selling a car in the UK, the vehicle’s MOT history plays a crucial role in determining trust and value. One of the biggest red flags in this history is a mileage discrepancy. Whether caused by genuine error or deliberate tampering, inconsistencies in recorded mileage can impact both MOT results and resale prospects.

What Is a Mileage Discrepancy?

A mileage discrepancy occurs when the mileage recorded during an MOT test does not match the logical progression from previous records. For example, if a vehicle’s 2023 MOT shows 60,000 miles but its 2022 MOT recorded 65,000 miles, this would raise questions. Such differences could indicate a simple administrative error or, in more serious cases, odometer fraud.

How MOT History Records Mileage

Every time a vehicle undergoes an MOT test, the tester logs its mileage into the DVSA (Driver and Vehicle Standards Agency) database. This information is public and can be checked online via the Check MOT service. These records are used by potential buyers, insurers, and dealers to assess a car’s condition and usage pattern.

Causes of Mileage Discrepancies

Mileage discrepancies can arise from several factors:

• Clerical Errors: Mistyped digits during MOT recording.
• Odometer Replacement: If an odometer is replaced and not set to the original reading.
• Odometer Tampering: Illegal rollback to make the car appear less used.
• Instrument Cluster Faults: Electrical issues causing inaccurate readings.

The Impact on Resale Value

A mileage discrepancy can significantly reduce a car’s resale value. Buyers often see it as a sign of possible fraud or poor maintenance history. Even if the discrepancy is a genuine mistake, it can still discourage potential buyers and lead to lower offers.

In some cases, dealerships may refuse to take the car in part exchange, or may only offer a reduced trade-in value to cover the perceived risk.

Legal and Insurance Implications

If a mileage discrepancy is found to be the result of deliberate tampering, it’s considered a criminal offence in the UK. Convictions can lead to fines or even imprisonment. Furthermore, insurance companies may decline coverage or void policies if they believe mileage information was falsified.

How to Protect Yourself

• Check MOT History: Always verify mileage records before buying a used vehicle.
• Request Service Records: These can help confirm actual mileage.
• Report Errors Promptly: If you spot a mistake in your MOT record, contact the DVSA to have it corrected.
• Avoid Suspicious Deals: Be wary of cars priced significantly below market value with vague mileage information.

Final Thoughts

Mileage discrepancies can cast doubt on a car’s reliability and honesty of its history. By regularly checking MOT history and ensuring accurate records, you can protect your vehicle’s value and avoid legal complications. Whether you’re buying or selling, mileage integrity is key to trust in the UK car market.
