01
Check the MOT history
Look at failures, advisories, mileage records and recurring problems. A clean current MOT is useful, but the full history usually tells a better story.
USED CAR CHECKS UK
How to check a used car before viewing or buying.
Buying a second-hand car in the UK can involve incomplete adverts, unclear history and expensive hidden problems. This guide explains the checks that should happen before you spend money or travel to view a car.
02
Compare mileage with age and condition
Mileage should make sense for the age, service history, MOT records and visible condition of the car. Sudden gaps or unusual patterns deserve closer attention.
03
Read the advert carefully
A good advert should be specific. Vague descriptions, missing service details, unclear ownership history or poor photos can make the viewing less predictable.
04
Understand model-specific risks
Different cars have different common issues. Timing chains, gearboxes, cooling systems, diesel emissions equipment, suspension wear and electrical faults can vary by model.
05
Check ownership and paperwork
The V5C, VIN, service history, receipts and seller details should all make sense together. Inconsistencies should be treated seriously.
06
Prepare questions before viewing
Good preparation helps avoid wasting time. Ask about service records, repairs, warning lights, tyres, brakes, clutch, timing belt or chain work and known issues.
Warning signs
When to slow down or walk away.
One warning sign does not always mean a car is bad, but patterns matter. If the advert, history and seller answers do not line up, the risk is usually higher.
The seller avoids direct questions.
The MOT history shows repeated advisories that were never fixed.
Mileage records look inconsistent.
The advert gives very little information.
The car is priced far below similar examples without a clear reason.
The service history does not match the age, mileage or type of vehicle.
