The best way to buy a used car from a dealer is to research the dealer first, check the vehicle's history using its registration number, inspect and test drive the car properly, and then pay in a traceable way with everything agreed in writing. Follow the steps below in that order and you will avoid most of the common problems.
Buying from a dealer usually gives you stronger legal protection than a private sale, but it does not replace your own checks. A friendly salesperson and a shiny forecourt tell you very little about the car's past.
1. Research the dealer before you visit
Read recent reviews on more than one site, and look at how long the business has been trading. If it is a limited company, you can look it up on Companies House. Check whether it belongs to a recognised motor trade code of practice, such as one backed by The Motor Ombudsman. Membership is not a guarantee of quality, but it gives you a complaints route if things go wrong. Be cautious of dealers who rush you or say another buyer is on the way.
2. Check the vehicle's history before you travel
Do this before you spend time and fuel on a viewing. A history check can show problems that are not visible on the forecourt. Key things to look at include:
- MOT history: past failures, advisories and recorded mileage, which come from DVSA data. Repeated advisories for corrosion or suspension can point to costly work ahead.
- Mileage: readings that go down or look inconsistent between MOTs and services can suggest clocking.
- Insurance write-off records: the MIAFTR database records categories A, B, S and N. Cat A and B cars should never return to the road, while Cat S (structural) and Cat N (non-structural) can be repaired and sold. They are worth less and need extra scrutiny.
- Stolen marker: whether the car is flagged on the Police National Computer (PNC).
- Outstanding finance: a car with unpaid finance may not legally belong to the seller, and the finance company could try to recover it.
- Previous keepers and plate changes: a lot of owners in a short time, or a changed registration, deserves a question.
You can check the vehicle's registration on motorpeek.com to see this kind of information in one place. We are an independent service and not a government body, so also use the free MOT history service on GOV.UK to compare what you find.
3. Inspect the car in person
View the car in daylight and dry weather, as rain and darkness hide paint and bodywork flaws. Walk around it slowly and look at:
- Uneven panel gaps, mismatched paint shades or overspray on rubber seals, which can suggest accident repairs.
- Tyre wear. Uneven wear can point to alignment or suspension faults, and four different brands can suggest cost-cutting.
- Warning lights that stay on when the engine is running.
- Damp smells, stained carpets or misted lights, which may mean water leaks.
- Wear on the pedals, steering wheel and driver's seat. It should roughly fit the stated mileage.
- The service book or digital service record, plus both keys.
Ask to see the V5C logbook. Check that the VIN and registration match the car and the paperwork, and that the details are consistent with what you were told.
4. Take a proper test drive
Ask for the engine to be cold when you arrive, because some faults show up only on a cold start. Drive on a mix of roads, including a faster section if possible. Listen for knocks, whining or rattles, and check that the car does not pull to one side under braking. Test the gearbox or clutch, air conditioning, windows, mirrors and all electrics. Make sure you are insured to drive it before you set off.
5. Ask what the dealer has done and what is covered
Ask what checks and repairs the dealer carried out, whether there is a fresh MOT, and when the car was last serviced. If a warranty is included, read the terms. Look at what it excludes, any claim limits and whether you must use the dealer's garage for repairs. For older cars, ask whether the cambelt has been changed, as that can be an expensive job.
6. Know your consumer rights
Under the Consumer Rights Act 2015, a car bought from a dealer must be of satisfactory quality, fit for purpose and as described. If it has a fault that was present at the time of sale, you generally have a short-term right to reject it within 30 days. After that, you can usually ask for a repair or replacement, and in the first six months the dealer normally has to show the fault was not there when you bought it. How these rights apply depends on the circumstances, so get advice from Citizens Advice if you are unsure. Paying part or all of the price by credit card can also give extra protection under Section 75 for purchases between £100 and £30,000.
7. Pay safely and keep the paperwork
- Pay by card or bank transfer so there is a record, and avoid handing over large sums in cash.
- Get an invoice showing the registration, VIN, mileage, price and any extras the dealer promised, such as a service or new tyres.
- Screenshot or save the original advert so you can prove how the car was described.
- Check that you receive the V5C paperwork, spare key and service history that were agreed.
Red flags to walk away from
- The dealer will not let you see the V5C or the service history.
- You are pushed to pay a deposit immediately.
- The history shows a mismatch in mileage, an unexplained write-off record or finance.
- The price is far below similar cars with no clear reason.
If something feels wrong, you can walk away. There are plenty of other cars for sale.
Frequently asked questions
What should I check when buying a used car from a dealer?
Check the vehicle's history (MOT records, mileage, write-off category, stolen marker and outstanding finance), then inspect the car in daylight and take a test drive. Ask to see the V5C and service history, and get all promises in writing.
Can I return a used car to a dealer if it has a fault?
Under the Consumer Rights Act 2015, you generally have a short-term right to reject a faulty car within 30 days of purchase. After that, the dealer usually gets a chance to repair or replace it. The outcome depends on your circumstances, so get advice from Citizens Advice if the dealer disputes it.
Is it safer to buy a used car from a dealer than privately?
Dealers must follow consumer law, so you normally have stronger protection than in a private sale, where the car only has to match its description. This does not guarantee a problem-free car, so you still need to check the history and inspect it yourself.
