Vehicle guide
Vehicle self-inspection checklist
Inspect the vehicle in daylight on dry, level ground and compare it directly with the advert, V5C, history report and service evidence. Work systematically through identity, bodywork, tyres, cabin, cold start and road test. Record what you observe, but use a qualified inspector for structural, mechanical, diagnostic or high-voltage concerns.

Use the same route around every vehicle

Read the three steps
- 01 · OutsideStart in daylight
Walk around dry bodywork and compare paint, panels, glass, lights and tyres.
- 02 · InsideCheck controls and cold start
Look for warning lights, unusual noises and equipment that does not match the advert.
- 03 · RoadRecord, then get help
Note every concern and use a qualified inspector where diagnosis is needed.
A structured inspection helps a buyer compare the advert, paperwork and actual vehicle consistently. It cannot replace specialist diagnosis where a fault, repair or safety concern needs expert assessment.
Prepare and confirm the vehicle
- 1
Arrange to see the vehicle in daylight, when the bodywork is dry and, where practical, before the engine has been started.
- 2
Take the saved advert, report and seller’s written answers so you can compare each claim with the vehicle.
- 3
Match the registration and accessible VIN markings with the original V5C, MOT history and report before relying on the remaining results.
- 4
Ask the seller before operating controls, opening compartments or driving the vehicle.
Inspect the exterior and structure safely
- 1
Walk around the vehicle slowly and compare panel gaps, paint colour, gloss and texture from both sides.
- 2
Look for overspray, corrosion, cracked glass, damaged lights, fluid beneath the vehicle and disturbed fasteners or seam sealer.
- 3
Check every tyre for tread, cuts, bulges, uneven wear and compatible size and rating on each axle; use the manufacturer’s pressure information rather than the maximum printed on the tyre.
- 4
Never crawl beneath a vehicle supported only by a jack, touch hot or moving components, open pressurised systems or handle orange high-voltage cables.
Check the cabin, equipment and cold start
- 1
Check seats, seat belts, locks, windows, mirrors, lights, wipers, heating, air conditioning, cameras and other equipment included in the sale.
- 2
Confirm that the odometer, trim and fitted options agree with the advert and documents.
- 3
Before starting, check that the engine is genuinely cold where practical; then observe starting behaviour, smoke, unusual noises and warning-light operation.
- 4
If a warning light remains on or a fault message appears, photograph it safely and ask for diagnostic or repair evidence rather than accepting a verbal reset explanation.
Road-test and review the evidence
- 1
Drive only with the seller’s permission and confirmed insurance covering you for that specific vehicle.
- 2
Use a safe, varied route long enough to assess low-speed manoeuvring, steering, brakes, clutch or transmission, suspension, acceleration and behaviour after warming up.
- 3
Afterwards, recheck warning lights, fluid leaks, smells, cooling behaviour and anything that changed during the drive.
- 4
Write down each concern and decide whether it needs documentary evidence, a repair estimate or an independent inspection before any deposit or purchase payment.
Your practical checklist
Tick each item as you work through the vehicle, documents and evidence. An unticked item stays open—it does not become a clear result.
Useful sources and next steps
Questions buyers ask
Should I inspect a used vehicle in rain or darkness?
Avoid relying on a viewing where poor light or wet bodywork hides paint, glass, tyres or panel condition. Arrange another daylight inspection if the conditions prevent a useful comparison.
Can my own inspection replace a professional one?
It is a valuable first check, but not where structural repairs, mechanical faults, diagnostic issues, specialist conversions or high-voltage systems require qualified assessment.
Should the engine be cold when I arrive?
A cold start can reveal behaviour hidden once an engine is warm. Ask in advance, then check cautiously whether it appears cold; do not touch hot or moving parts.
What should make me stop the test drive?
Stop safely if the vehicle develops a serious warning, unsafe steering or braking, overheating, heavy smoke or another condition that makes continuing unwise. Do not attempt to diagnose it at the roadside.
Check the vehicle in this guide
Start with the free official-data snapshot. We will keep anything not returned clearly marked as unknown.
What vehicle are we looking at?
Enter the registration, or upload a clear photo of the number plate. You will confirm anything read from an image before a check runs.
Images are processed only to find registration candidates and are not retained by Car Assistant. We do not extract other V5C details.
