Check a second-hand car before you buy it
Before you travel to view a second-hand car, the useful question is not only whether it has an MOT. You need to know whether the advert, mileage, model risks and seller evidence make the car worth your time.

Guide
What to check
A UK buyer guide for checking a second-hand car before viewing: registration, MOT history, mileage, seller evidence, model problems and negotiation signals.
Start with the registration
A UK registration can provide useful vehicle identity and MOT context. Duewise uses it as the starting point, then checks the specific model instead of giving generic used-car advice.
- Confirm the make and model match the advert.
- Review MOT mileage and repeated advisories.
- Avoid wasting time if the vehicle cannot be identified properly.
Mileage is not just a number
The same mileage can mean different things on different cars. Duewise looks at age, model type, likely wear stage and evidence gaps so the buyer can ask better questions before viewing.
- High mileage may be acceptable with strong maintenance evidence.
- Low mileage can still be risky if servicing is missing.
- Known weak points matter more at certain mileage stages.
Ask for proof before travelling
Seller claims should become evidence requests. Ask for dated invoices, service records, MOT repair proof, timing-chain or timing-belt evidence where relevant, and gearbox service history where the model needs it.
Use the check to decide your next action
A good pre-viewing check should help you decide whether to shortlist, inspect carefully, negotiate or walk away. Duewise turns the data into buyer actions instead of leaving you with disconnected facts.
FAQ
Common questions
What should I check before buying a second-hand car?
Check the registration, MOT history, mileage pattern, service evidence, seller claims, known model problems, tyres, brakes, leaks, warning lights and test-drive behaviour.
Is a second-hand car with a clean MOT safe to buy?
A clean MOT is useful, but it is not a full mechanical inspection. You still need service evidence, model-specific checks and a proper viewing or inspection.
