How to Inspect a Used Car – ChrisFix Checklist for UK Buyers

ChrisFix’s popular video walkthrough can be adapted for the UK market. Start by gathering the vehicle’s registration number, V5C logbook and any MOT certificates, then move through the exterior, interior, mechanical and paperwork checks. Following this checklist will help you spot hidden problems before you sign the contract.

1. Quick paperwork scan

V5C registration document – confirms the registered keeper and whether the seller is the legal owner.
MOT history – use the DVSA MOT test service to view the last 10 results and any advisory notes.
Insurance write‑off status – check the MIAFTR database for Category A, B, S or N marks.
PNC stolen marker – a quick check on the Police National Computer can reveal a stolen vehicle.
Finance check – ensure there is no outstanding finance that could repossess the car.

2. Exterior inspection

Walk around the car under good lighting. Look for mismatched panels, uneven gaps or fresh paint that may hide rust or accident damage.

Check the condition of the tyres – tread depth should be at least 1.6 mm and the wear pattern even.
Inspect the wheel rims for bends or corrosion.
Examine the windscreen and windows for chips, cracks or signs of previous replacement.
Test all lights – head‑lamps, indicators, brake lights and reverse lights – using the car’s controls.
Verify the VIN (Vehicle Identification Number) on the chassis matches the one on the V5C.

3. Interior inspection

Open every door, the boot and the bonnet. Look for water stains, mould or unusual smells that could indicate leaks.

Check the seat belts for fraying and ensure they lock on sudden tension.
Operate the infotainment system, climate control, windows and mirrors to confirm full functionality.
Count the odometer reading and compare it with the mileage recorded on the service book and MOT certificates – a discrepancy of more than 10 % may suggest clocking.
Note the number of previous keepers listed on the V5C; a high number can be a red flag.

4. Engine bay and under‑car review

With the engine cool, open the bonnet and look for leaks, corrosion or loose hoses.

Check oil level and colour – it should be amber and free of metal particles.
Inspect the coolant reservoir for proper level and a clean, non‑sludgy appearance.
Examine the battery terminals for corrosion.
Listen for abnormal noises when the engine is started – knocking, ticking or excessive vibration can indicate internal wear.
Pull the dipstick and note the oil condition; dark, gritty oil may point to neglect.

5. Test drive

Take the car on a varied route – city streets, a short stretch of dual carriageway and a quiet road.

Feel for smooth gear changes in both manual and automatic transmissions.
Check the brakes for consistent pedal feel and no pulling to one side.
Listen for rattles, squeaks or wind noise that could reveal loose trim or suspension issues.
Observe the steering response – there should be no excessive play.

6. Final verification

After the inspection, run a comprehensive vehicle history check on motorpeek.com. The report will pull together DVLA registration data, MOT history, insurance write‑off status, finance alerts and any recorded mileage discrepancies, giving you a single source of truth before you decide.

Remember, no visual inspection can replace a full mechanical appraisal, but this checklist equips you with the knowledge to ask the right questions and avoid costly surprises.

Frequently asked questions

What paperwork should I check when buying a used car in the UK?

You should review the V5C registration document, the latest MOT certificates, any service history, and confirm there are no outstanding finance or insurance write‑off markings. Also check the PNC stolen marker if possible.

How can I tell if a car’s mileage has been tampered with?

Compare the odometer reading with the mileage recorded on the service book, MOT history and any previous vehicle checks. A difference of more than 10 % or inconsistent entries can indicate clocking.

What does a Category S write‑off mean for a used car?

Category S indicates structural damage that has been repaired. The car is road‑worthy but may have a reduced value and could have lingering safety concerns, so a thorough inspection and a full history check are essential.
