Disputes over second-hand car purchases are one of the most common consumer complaints in the UK. Whether the car has undisclosed mechanical problems, a mileage discrepancy, outstanding finance, or a different service history from what was described, your rights depend significantly on whether you bought from a dealer or a private seller.
Buying from a dealer
When you buy a car from a motor dealer — including online dealers — the Consumer Rights Act 2015 applies. The car must be of satisfactory quality, fit for purpose, and as described. Within the first 30 days you have the right to reject the car and receive a full refund if it is not of satisfactory quality. Between 30 days and six months, the dealer has one chance to repair or replace before you can seek a refund. After six months, you must prove the fault existed at the time of sale.
What counts as unsatisfactory quality?
A car is unsatisfactory if a reasonable person, knowing the price paid, the age, and mileage, would consider it unacceptable. Minor faults consistent with age and mileage may not be sufficient — the question is whether the defect goes beyond what the buyer should reasonably have expected given what they paid. Significant mechanical failures shortly after purchase, safety defects, or undisclosed accident damage are likely to meet this threshold.
Buying from a private seller
Private sellers are not bound by the Consumer Rights Act. The principle of caveat emptor — buyer beware — applies. However, a private seller still cannot misrepresent the car. If they make false statements about the mileage, service history, accident history, or condition — statements you relied on when buying — you may have a claim in misrepresentation. This allows you to rescind the contract and recover the purchase price, or claim damages.
Outstanding finance
If the car was sold subject to a finance agreement that the seller failed to disclose, the finance company retains ownership and can repossess the vehicle from you. You may then have a claim against the seller for the loss of the car. Running a HPI check before buying will reveal any outstanding finance, previous write-offs, or stolen vehicle markers — it costs around £20 and is money well spent.
Clocking
Clocking — winding back the odometer to show a lower mileage — is fraud. It is a criminal offence under the Fraud Act 2006 and the Trade Descriptions Act 1968. It also gives you a claim for misrepresentation. Evidence of clocking includes inconsistencies between the displayed mileage and service records, MOT history from the DVLA website, and wear and tear inconsistent with the displayed mileage.
Car disputes can involve significant sums. A consumer rights solicitor can advise on your strongest route to a refund or compensation.
