Paperwork first
Ask to see the V5C and compare the registration, VIN, make, model and colour with the car. Check that the advert and seller’s account of the car are consistent.
Outside the car
Look at tyres, wheels, glass, lights, panel gaps, paint finish and signs of leaks. Uneven wear or inconsistent finishes are useful prompts for more questions.
Inside the car
Try the equipment you care about: heating, air conditioning, windows, locks, seats, infotainment and warning lights. Check that all keys and documents promised are present.
On the road
If you can take an insured test drive, notice how the steering, brakes, clutch or gearbox, engine and suspension feel. A test drive is not a mechanical inspection, but it can identify questions worth following up.
Seller conversation
Ask about recent servicing, faults, repairs, ownership and why the car is for sale. Keep important answers in writing and do not let urgency replace proper checking.
Practical checklist
Frequently asked questions
What should make me walk away?
Inconsistent paperwork, pressure to pay quickly, warning lights, unclear history or a seller who will not allow sensible checks are all reasons to pause.
Can I take a mechanic?
Ask the seller. If you are unsure about condition, an independent inspection can provide useful evidence.
