Your rights with a dealer
A dealer must sell you a car that matches its description, is fit for the purpose you bought it for, and is of satisfactory quality. If it isn't, you have rights to put it right. For the detail on your case, Citizens Advice is the place to check.
Many dealers also offer a warranty, but cover varies widely. Get the warranty terms in writing before you pay, and check what's covered, for how long, and who backs it. A warranty is never a reason to skip the checks.
Before you sign: - Get the description, mileage and any known faults in writing. - Run a free car check on the mileage and MOT history. - Check the VIN on the car matches the V5C. - Check for open recalls. Recall repairs are free at a franchised dealer.
Buying privately
Private sales are usually cheaper than dealer sales. But you buy the car as it is, with no dealer warranty to fall back on, so checks matter even more.
Do every check before you pay. Start with the free car check: it shows MOT history and mileage at each test, with clocking warnings. A drop between MOTs is the classic sign. Then check the V5C. The name and address should match the seller's ID, and the VIN should match the car on the windscreen, door pillar and logbook.
Watch for finance and write-offs. If the car is on hire purchase or PCP, the finance company may own it until the last payment. A Full Check (£9.99) covers finance, stolen and write-off records. Driving without a valid MOT can bring a fine of up to £1,000, and tax doesn't transfer, so tax the car before you drive it.
Which to choose
Dealers usually cost more, but they give you more legal protection and often a warranty. Private sales are cheaper, but you buy the car as it is. If budget is your main concern, a private sale can work. If you want peace of mind, a dealer is the easier choice.
Either way, check before you pay. The average car fails 28.4% of first MOT tests, so a clean look isn't enough. Start with the free check, which covers MOT history, mileage at every MOT, tax and ULEZ.
For a private sale, the extra checks matter most. A Full Check (£9.99) shows finance, stolen and write-off records. Then check the V5C: the name and address should match the seller's ID, and the VIN should match the car. If anything doesn't add up, walk away.
