Buying a Used Car in the UK: The Complete Checklist

Buying second-hand can save thousands, but a car with hidden finance, a past write-off or a wound-back mileage can cost you dearly. Work through this checklist before you hand over any money. Tick items off as you go: your ticks are saved on this device, and the page prints neatly to take with you.

Before you go: budget and research

Set a total budget that includes insurance, road tax (VED), fuel and a servicing fund, not just the price
Get insurance quotes for the exact make, model and engine before you commit: they vary a lot
Look up the model's common faults and recalls, and what a fair price is for its age and mileage
Decide whether you'll buy from a dealer (more legal protection) or a private seller (often cheaper, fewer rights)

Free checks on GOV.UK (do these first)

Check the MOT history using the registration: gov.uk/check-mot-history. Look at past failures, advisories and the mileage recorded at each test
Make sure the mileage rises steadily from test to test: a drop or a long gap is a red flag
Check the tax and MOT status and the vehicle details (colour, engine size, first registered): gov.uk/check-vehicle-tax
Make sure the details match the advert. A different colour or engine size can mean a cloned car

🔍 Do a full vehicle history check

The free GOV.UK checks don’t tell you about outstanding finance, insurance write-offs, stolen markers or number plate changes. A paid history check does, and costs far less than getting it wrong.

We recommend carVertical: enter the registration and you get a report covering outstanding finance, write-off records, stolen markers, mileage history and more.

Other providers such as HPI, the AA and the RAC offer checks too. Whichever you use, make sure it covers outstanding finance, write-offs and stolen markers.

Paperwork and identity checks at the viewing

View the car at the seller's home address, in daylight, not in a car park or lay-by
Ask for the V5C logbook: the name and address should match the seller and where you're viewing
Check the VIN (vehicle identification number) on the V5C matches the car: usually at the bottom of the windscreen, on the door pillar and under the bonnet
Hold the V5C up to the light and check it has a DVLA watermark. Never buy without a V5C
Go through the service history, receipts and old MOT certificates: they should match the mileage
Check there are two keys, plus the locking wheel nut key if fitted

Looking over the car

Start the engine from cold (put your hand on the bonnet first): listen for rattles and watch for smoke
Check every warning light comes on with the ignition and then goes out
Look for uneven panel gaps, mismatched paint or overspray: signs of accident repairs
Check the tyres: at least 1.6mm of tread (the legal minimum) across the central three-quarters, with no cracks, and even wear (uneven wear can mean alignment problems)
Look under the oil filler cap: a creamy, mayonnaise-like residue can point to head gasket trouble
Check for damp carpets, musty smells or condensation, which can mean leaks
Test the electrics: windows, mirrors, lights, wipers, air conditioning, heated screens and the infotainment

The test drive

Make sure you're insured to drive it: many policies only give third-party cover on other cars, or none
Drive on a mix of roads, including a faster road, for at least 15-20 minutes
Brakes should feel firm and stop straight, with no pulling, grinding or juddering
Gears should change smoothly. On a manual, a clutch that bites very high can mean it needs replacing soon
The car should track straight with no knocks over bumps, and the steering wheel should be centred
Afterwards, look under the car for any fresh drips

Negotiating and paying safely

Use anything you've found (advisories, worn tyres, a service due) to negotiate the price
Avoid carrying large amounts of cash. A bank transfer gives you a record. Be wary of anyone who wants an unusual payment method
Get a written receipt with the date, price, registration, VIN, and both names and addresses
Dealer: under the Consumer Rights Act 2015 the car must be of satisfactory quality, fit for purpose and as described, and you have a short-term right to reject within 30 days
Private sale: the car must be as described and the seller must have the right to sell it, but you have far fewer rights, so the checks above matter even more

After you buy

Tax the car before you drive it: road tax doesn't transfer to a new keeper
Make sure your insurance is in place before you drive away
The seller should tell DVLA about the change of keeper, and give you the new keeper slip (V5C/2) to keep until your new V5C arrives
Book a service if one is due, and note the date of the next MOT

🚘 Red flags: walk away if…

There's no V5C, or the seller's details don't match it
The VIN doesn't match the paperwork, or looks tampered with
The MOT history shows the mileage going down
The seller won't let you view at their home or rushes you
The history check shows outstanding finance, a write-off or a stolen marker
