Understanding Used Car Disputes

When buying a used car from a dealer, you have significant legal protection under the Consumer Rights Act 2015. Cars must be as described, of satisfactory quality, and fit for purpose.

Common scenarios: - Car misrepresented (hidden damage, wrong history) - Mileage fraud (clocked car) - Dealer failed to deliver vehicle after deposit - Warranty disputes - Hidden finance or outstanding debts on vehicle

Key timeframes: - 30 days: Right to reject for full refund - 6 months: Fault presumed to have existed at sale

Evidence You Need

Essential evidence: - Sales agreement and receipt - Original advertisement (screenshot or printout) - Independent inspection report - MOT history (check online) - Service history (if claimed)

Helpful evidence: - Communication with seller - HPI check showing outstanding finance - Photos of defects - Expert mechanic assessment

MOT history check: Go to gov.uk and enter the registration number. This shows mileage at each MOT - crucial for mileage fraud cases.

What You Can Claim

Typical claim value: £500 - £10,000

You can claim: - Full refund (if rejected within 30 days or fault cannot be fixed) - Difference in value (car worth less than represented) - Cost of repairs for faults - Consequential losses (inspection costs, etc.)

Mileage fraud calculation: The difference between what you paid and what the car is worth with its true mileage. Valuation guides can help establish this.

Types of Used Car Claims

Mileage fraud: If the mileage has been reduced ("clocked"), you can claim the difference in value. Check MOT history for jumps in recorded mileage.

Hidden damage: If previous accident damage was not disclosed and affects value or safety, claim for reduced value or rejection.

Mechanical faults: If faults existed at the time of sale (not caused by subsequent use), the dealer must repair, replace, or refund.

Finance problems: If the car has outstanding finance and the lender repossesses it, claim your full purchase price from the dealer.

Warranty refusal: If warranted repairs are refused without valid reason, claim the repair cost.

Frequently Asked Questions

Check the MOT history at gov.uk - it shows mileage at each test. If mileage goes down between tests, it has been clocked. Also check service records and look for wear inconsistent with claimed mileage.
