SECOND HAND CAR CHECKLIST UK

Second-hand car checklist before viewing or buying.

A second-hand car can look good in photos and still carry hidden risk. This checklist helps UK buyers prepare before contacting a seller, viewing a car or making a buying decision.

Check a car with Duewise Used-car checks guide

Before you contact the seller

Check whether the advert gives enough detail about service history, ownership, mileage and condition.
Compare the price with similar cars of the same age, mileage, engine and trim.
Look for missing photos, vague descriptions or claims that are not supported by evidence.
Check whether the car has known model-specific issues that could be expensive.

MOT and mileage checks

Review the full MOT history, not just the current MOT result.
Look for repeated advisories, corrosion warnings, tyre issues, brake wear or suspension problems.
Check that mileage records increase logically over time.
Be careful with long gaps, sudden mileage changes or a history that does not match the advert.

Paperwork and ownership

Check that the V5C details match the car and the seller situation.
Ask for service history, invoices and proof of major maintenance.
Check that the VIN on the car matches the paperwork.
Avoid pressure to buy before you have seen the documents properly.

Questions to ask before viewing

Ask why the car is being sold.
Ask how long the seller has owned it.
Ask about warning lights, faults, recent repairs and known issues.
Ask whether timing belt, timing chain, clutch, gearbox, brakes or tyres have needed work.

At the viewing

View the car in daylight where possible.
Check body panels, tyres, brakes, lights, interior wear and signs of accident damage.
Start the engine from cold if possible.
Listen for unusual noises and check for warning lights.

During the test drive

Check clutch feel, gearbox selection, steering, brakes and suspension noise.
Make sure the engine pulls smoothly and temperature stays stable.
Check for smoke, hesitation, vibration or warning messages.
Do not ignore problems just because the car looks good in photos.

Warning signs

Red flags when buying a second-hand car.

One issue does not always mean the car is bad, but several warning signs together usually mean the risk is higher than the advert suggests.

The seller gives rushed or vague answers.

The price is unusually low without a believable reason.

The MOT history shows repeated unresolved advisories.

The service history is missing or does not match the mileage.

The seller refuses a proper viewing or test drive.

The paperwork, VIN, advert and seller details do not line up.

There are warning lights on the dashboard.

The car has signs of poor repair, accident damage or neglected maintenance.
