How to Check a Car Before Buying It Privately

Buying a car privately can save you money compared with a dealer, but it also means fewer legal protections if something goes wrong. A thorough check before you hand over any cash will catch the most common problems: outstanding finance, clocked mileage, hidden accident damage, and a lapsed MOT.

Start With the Free Online Checks

Before you even travel to see the car, run the registration number through the DVLA's free vehicle enquiry service on gov.uk. This shows you the make, fuel type, engine size, colour, CO2 figure and the current MOT and tax status. It takes about thirty seconds and has already saved many buyers an awkward conversation on the doorstep.

The DVSA's free MOT history checker (also on gov.uk) goes further and shows every MOT result since 2005, the mileage recorded at each test, every failure reason and every advisory. This is one of the most useful free tools available to a UK buyer. Look for:

• Mileage that goes backwards or stays flat. Genuine mileage climbs consistently. If the car shows 80,000 miles at one test and 74,000 at the next, that is a strong indicator of clocking or a tester error. Either way, walk away or demand an explanation.
• Repeated advisories on the same component. An advisory is not a failure, but it records a defect worth watching. The same suspension or brake advisory appearing across three consecutive tests suggests a seller who never fixes anything.
• Recent failures for serious items. A failure for dangerous or major defects (the two categories that prevent a pass) tells you how the car has been maintained.

These checks are free from the registration number and take only a few minutes. Do them before you make any arrangements to view the car.

What the Free Check Does Not Cover

The DVLA record does not include the model name, service history, or any financial or legal markers. To find out whether the car has outstanding finance, has been stolen, or has been written off and categorised (Category A, B, S or N, or the older C and D on pre-2017 cars), you need a paid history check from a provider that queries the relevant databases. That step is strongly recommended for any private purchase. If there is outstanding finance registered against the car, the finance company still owns it and can repossess it from you, regardless of how much you paid the seller.

Verify the Paperwork Matches the Car

When you arrive, check the V5C (the registration document) carefully.

• The VIN on the V5C must match the plate stamped on the car's chassis or door sill and the one visible through the windscreen at the base.
• The engine number on the V5C should match the number on the engine itself (usually stamped on the block).
• The colour, fuel type and engine size on the V5C must match what you can see and what the DVLA record shows.
• The registered keeper's name and address on the V5C should match the person selling the car and the address where the car is kept. Be cautious if the seller asks you to meet somewhere other than their home.

A V5C can be a copy or a forgery. Check the watermark and the unique reference number. If the document looks wrong or the seller cannot produce it, do not buy.

The Physical Inspection

You do not need to be a mechanic to spot the most common problems. Work through these methodically.

Bodywork and panels

• Look along the car from each corner in good light. Ripples, mismatched paint or uneven panel gaps indicate previous accident repair.
• Check that the door, bonnet and boot shut lines are even all the way round.
• Run a magnet (or a fridge magnet in a cloth) along the sills and lower panels. It will not stick to filler.

Under the bonnet

• The engine should be clean but not suspiciously steam-cleaned just before sale. A freshly washed engine can hide oil leaks.
• Look for oil or coolant residue around hoses, the cam cover and the radiator.
• Check the oil on the dipstick: black and gritty is poor maintenance, milky or creamy suggests a head gasket problem.

Interior and electrics

• Check every electric window, the air conditioning, heated seats, and all dashboard warning lights. Start the car from cold if you can, as some faults only show up then.
• Look at seat bolsters and the steering wheel for wear that does not match the claimed mileage.

On the road

• A test drive should include a motorway-speed section if possible. Listen for vibration, pulling to one side, hesitation under acceleration and any warning lights that appear under load.
• Brakes should pull up straight and not squeal persistently.

Check the MOT and Tax Are Current

Driving a car with a lapsed MOT is an offence, except when travelling directly to a booked MOT test. Vehicle tax does not transfer when a car is sold, so the seller's tax ends on the day of sale and you must tax the car before you drive it away. Both the MOT expiry date and the tax status are visible on the free DVLA check.
