Buying a used car privately or from a dealer comes with real risk if you do not know what to check. None of the steps below require any mechanical expertise, just a methodical run-through before you commit to anything.
Before you go and see the car
- Check the MOT history. The official government MOT history check is free and shows every past test, including mileage recorded at each one, pass and fail results, and any advisories. Recurring advisories for the same issue are worth asking the seller about directly.
- Check for outstanding finance and write-off history. A history check, sometimes called an HPI check, will flag whether the car has outstanding finance owed against it, has been recorded as stolen, or has a write-off category from a previous insurance claim. Buying a car with undisclosed outstanding finance can mean the finance company has a legal claim to repossess it, even from an innocent buyer.
- Compare the mileage trend. Look at the mileage recorded at each MOT in the history check. A sudden jump or an inconsistent pattern compared to the advertised mileage is a clear red flag.
When you see the car in person
- Check the VIN matches. The 17-character Vehicle Identification Number should match across the V5C logbook, a plate under the bonnet or on the door sill, and often etched into the windscreen. A mismatch is a serious red flag.
- Confirm the seller's identity matches the V5C. For a private sale, the name and address on the green V5C logbook should match the seller you are dealing with. Be cautious of sellers who want to meet somewhere other than the registered address.
- Walk around in daylight. Look along each body panel from a low angle for ripples or colour mismatches, which can indicate previous accident repair. Check panel gaps are even on both sides of the car.
- Check tyre wear is even. Uneven wear across the tyre, or different wear front-to-back versus side-to-side, can point to alignment, suspension, or even accident-related issues.
- Check the service history. A full, stamped service history, ideally with receipts, tells you far more than the seller's word. Be wary of a car with no history at all, particularly if it is more than a few years old.
- Test everything electrical. Windows, mirrors, air conditioning, infotainment screen, all the warning lights illuminating briefly on startup and then going out. Anything that stays lit is worth asking about.
Always test drive it yourself. Cold start the engine if possible, since some issues like worn bearings or a failing turbo are more obvious on a cold start than once the engine has warmed up. Listen for unusual noises, test the brakes at a safe speed, and check the steering does not pull to one side.
Questions worth asking the seller directly
- Why are you selling it?
- Has it ever been in an accident, even a minor one?
- Is there any outstanding finance on it?
- Do you have the full service history and both sets of keys?
- Has anything significant been replaced recently, and do you have the receipts?
A straightforward, consistent answer is a good sign. Vague or shifting answers to any of these are worth taking seriously, even if everything else about the car looks fine.
Before you hand over any money
Get everything in writing, including the agreed price, the mileage, and any specific promises made about the car's condition or history. For a private sale, a simple written receipt signed by both parties, with the date, price, registration, and mileage, gives you some protection if anything turns out to be inaccurate later. Never transfer money before you have physically seen the car, the V5C, and confirmed the seller's identity.
