Check a Car Before Buying
Buying a used car without doing your homework is one of the most common ways people lose money. Here is a practical, step-by-step checklist of everything you should verify before handing over a penny.
1. Run a Vehicle History Check
Do this before you arrange a viewing. There is no point spending an hour travelling to see a car that turns out to have outstanding finance, a theft marker, or a serious write-off in its past. A VEHIXA full report from £11.99 covers outstanding HP and PCP finance, the Police National Computer stolen register, insurance write-off categories (Cat A, B, S and N), keeper history, number plate changes, and a current market valuation. Run it first and only proceed if the report is clean — or if you fully understand what any issues mean for the price.
2. Check the MOT History
MOT history is freely available from the DVSA and is included in every VEHIXA check. Go through it carefully. The mileage recorded at each annual test should increase steadily — any sudden drop suggests the odometer has been tampered with. Review past failure reasons and advisories too. Repeat advisories for the same item across multiple consecutive tests are a sign of deferred maintenance. Pay particular attention to anything related to brakes, suspension, steering, or corrosion.
3. Verify the Finance Position
Around 1 in 5 used cars advertised privately in the UK has outstanding finance secured against it. The finance company — not the person selling the car — is the legal owner until the debt is fully repaid. If you buy a car with outstanding finance, the lender is entitled to repossess it from you regardless of how much you paid. The seller can even be unaware of the problem if they inherited the car or bought it in good faith themselves. A finance check is not optional — it is essential.
4. Physical Inspection Checklist
History checks cover what is in the databases — a physical inspection covers what you can see and hear. When viewing the car, check these areas carefully:
Bodywork — look for mismatched paint, uneven panel gaps, or overspray on rubber seals and trim. These are signs of previous accident repair that may not be in any database. Check inside door shuts and under the bonnet for signs of welding or filler.
Tyres — check tread depth across the full width of all four tyres. Uneven wear on the inside or outside edges indicates alignment or suspension problems. Check the spare too.
Under the bonnet — look for oil leaks, coolant leaks, and corrosion. Check the oil on the dipstick and the coolant level. Mayonnaise-like residue under the oil cap can indicate a head gasket fault.
Interior — verify the mileage on the odometer matches the MOT history records. Check all electrics, including air conditioning, windows, lights, and the infotainment system.
5. Take a Thorough Test Drive
Never skip the test drive. Drive the car from cold if possible — many problems only appear before the engine is fully warmed up. Drive at a range of speeds, brake firmly (in a safe location), and test the steering. Listen for clunks, rattles, or grinding noises. If the seller is reluctant to let you drive it, treat that as a serious warning sign.
If you are not confident assessing a car mechanically, a pre-purchase inspection from the AA, RAC, or an independent mechanic typically costs £100–£200 and can save you from a much more expensive mistake.
