The best tips for buying a used car are simple: check the vehicle's history before you view it, inspect it in daylight, test drive it properly, verify the paperwork, and only pay when you're satisfied. Most expensive mistakes happen when buyers skip one of these steps because the car looks clean or the price seems good.
Below is a practical UK checklist you can follow, whether you're buying from a dealer, a garage or a private seller.
1. Set a realistic total budget
Don't stop at the asking price. Factor in insurance, road tax (VED), fuel, servicing and a small reserve for repairs. Get an insurance quote for the exact model before you commit, as some cars cost far more to insure than buyers expect.
2. Check the vehicle's history first
A history check can save you a wasted journey. It's worth running one before you view a car, because some problems can't be spotted by eye. Key things to look for:
- MOT history: DVSA records show past passes, fails and advisories. Repeated advisories for the same issue (corrosion, brakes, suspension) can signal neglect.
- Mileage: Compare MOT mileage readings over the years. A sudden drop or an odd gap can suggest clocking or a data error.
- Insurance write-off category: MIAFTR records show whether a car was declared a write-off. Cat A and B must not go back on the road (Cat B can be broken for parts). Cat S (structural) and Cat N (non-structural) can be repaired and driven, but they affect value and may affect insurance.
- Outstanding finance: If a car is still under finance, the lender may have a claim on it, even if you've paid the seller.
- Stolen marker: The Police National Computer (PNC) can flag vehicles reported stolen.
- Previous keepers: Many owners in a short period can be a red flag, though not always.
You can check the vehicle's registration on motorpeek.com to see this kind of information in one place. We're an independent service, not a government body, and no check can guarantee a car is problem-free, so treat it as one part of your research.
3. Ask the seller the right questions
Before travelling, ask why they're selling, how long they've owned it, whether there's a full service history, and whether there are any known faults or accident repairs. Vague or inconsistent answers are worth noting.
4. Inspect the car in good light
View in daylight and when the car is dry. Rain can hide paint flaws and dents. Check:
- Panel gaps, mismatched paint or overspray that might indicate accident repair
- Tyre condition and even wear (uneven wear can point to alignment or suspension problems)
- Rust around wheel arches, sills and door bottoms
- Warning lights that stay on after starting the engine
- Interior wear that doesn't match the claimed mileage, such as a very worn driver's seat or pedals
- Signs of leaks under the car or smoke from the exhaust
Ask to see the car start from cold. A warm engine can hide starting problems.
5. Check the paperwork carefully
The V5C logbook should show the seller's name and address, and these should match where you're viewing the car. Check that the registration, VIN and engine number match the car itself. Never buy a car without the V5C, and be wary of sellers who say it's in the post. Ask to see the service book, invoices and previous MOT certificates, and confirm the car has a valid MOT. Cars generally need their first MOT when they're three years old.
6. Take a proper test drive
Make sure you're insured to drive it, and ask the seller to confirm their insurance covers test drives. Drive on a mix of roads if you can. Listen for knocks, whining or grinding, and check that:
- The steering is straight and the car doesn't pull to one side
- The brakes feel firm and don't judder
- The clutch bites at a sensible point and gears change smoothly
- The air conditioning, windows, lights and electrics all work
7. Consider an independent inspection
For higher-value or more complex cars, a professional inspection from an independent garage or motoring organisation can uncover faults you might miss. It costs money, but it may be cheaper than a major repair later.
8. Know your rights
Buying from a dealer gives you more protection under the Consumer Rights Act 2015. The car must be of satisfactory quality, fit for purpose and as described. In private sales, your rights are more limited: the car must match the description, and the seller must have the right to sell it. Paying a deposit or part of the price by credit card may offer extra protection under Section 75 for eligible purchases, but check the terms with your card provider.
9. Negotiate and pay safely
Use any faults, advisories or upcoming service costs to negotiate. Avoid paying cash in an unfamiliar place, and be cautious of requests for urgent payment or deposits before you've seen the car. Bank transfer gives you a record. Get a written receipt that includes the date, price, registration, VIN and both parties' details.
10. After you buy
Make sure the keeper details are updated with the DVLA, either by completing the new keeper section of the V5C or using the online service. Arrange insurance before driving away, and set up road tax, as it doesn't transfer with the car.
Final thought
Don't let pressure or a bargain price rush you. If something doesn't add up, whether it's the paperwork, the history or the seller's story, it's fine to walk away. There are plenty of other cars for sale.
Frequently asked questions
What should I check first when buying a used car?
Start with the vehicle's history using its registration number: MOT records, mileage, write-off category, outstanding finance, stolen marker and previous keepers. Then check the V5C logbook matches the car and seller. Only after that is it worth viewing and test driving the car.
How can I tell if a used car has been in an accident?
Look for uneven panel gaps, mismatched paint, overspray and signs of repair, and check whether the car has an insurance write-off record such as Cat S or Cat N. Not all accident damage is recorded, so an independent inspection can help for higher-value cars.
Is it safer to buy a used car from a dealer or privately?
Dealers are covered by the Consumer Rights Act 2015, which requires cars to be of satisfactory quality, fit for purpose and as described. Private sales offer fewer protections, so the car must match its description and the seller must have the right to sell it. Whichever you choose, check the history and paperwork carefully.
