V5C registration certificate
Check the registration, VIN/chassis details and keeper information against the physical vehicle. A V5C records the registered keeper; it is not proof of legal ownership.

Your quick used car checklist
Before travelling, save the advert and check the MOT, mileage and history. At the viewing, match the VIN and paperwork, inspect the car and test drive it. Before paying, resolve warnings and keep a written receipt.

- Read the mileage as a timeline
- Run the important provenance checks
- Match the car to its documents
- Ask for evidence, not reassurance

PAPERWORK FOR BUYING A USED CAR
Check the documents as carefully as the vehicle.
The paperwork should support the story you are being told about the car. Do not rely on a single document in isolation: match the vehicle, seller, recorded history and supporting evidence before you pay.
MOT history and mileage
Review the MOT timeline and odometer readings for repeated advisories, failures or mileage inconsistencies that need an explanation.
Service and repair evidence
Ask for service records, maintenance invoices and evidence for repairs the seller says have been completed.
Finance settlement evidence
If finance is recorded or disclosed, do not rely on a verbal promise that it will be settled. Resolve the position with appropriate documentary evidence before completing the purchase.
Seller receipt
Keep a written record of the seller, vehicle, agreed price, date and any material representations made about the car.
Insurance and tax arrangements
Make sure you understand what you need to arrange before driving the vehicle away; do not assume the seller's arrangements transfer to you.
BEFORE YOU VIEW THE CAR
Start the investigation before you leave home.
A used-car purchase becomes easier to assess when you arrive already knowing the recorded history. Use the registration and available records to identify the questions that deserve an answer at the viewing.
Save the advert
Keep the seller's description, photographs, asking price and claims about service or repair history.
Check MOT + mileage
Read the records as a timeline rather than looking only at today's MOT status.
Prepare seller questions
Turn anything unusual in the history into a specific question you can ask face to face.
10-POINT CHECKLIST
Work through these before completing the purchase.
Check the advert before travelling
Compare the registration, make, model, age, fuel type, colour and specification shown in the advert. Save a copy of the advert and note any claims the seller makes about history, condition or recent work.
Check the MOT history
Look beyond whether the car simply has an MOT. Review failures, dangerous defects and advisories over time. Repeated advisories can be particularly useful because they give you specific areas to ask about and inspect.
Read the mileage as a timeline
Compare recorded odometer readings in date order. An unexpected reduction or inconsistency needs an explanation. Also consider whether the mileage claimed in the advert makes sense against the latest recorded reading.
Run the important provenance checks
Before committing money, check available records for outstanding finance, stolen status, insurance write-off history and other relevant lifecycle markers. An unavailable data source should not be treated as a clear result.
Match the car to its documents
At the viewing, compare the registration and available VIN/chassis information with the physical vehicle and V5C. Check that the seller's details and explanation of their relationship to the vehicle make sense.
Ask for evidence, not reassurance
If the history shows a previous failure, recurring advisory or other issue, ask what was repaired, when it was repaired and whether there is an invoice or other supporting paperwork.
Inspect the vehicle in daylight
Check body panels, paint consistency, tyres, wheels, lights, glass, interior wear and warning lights. Look for anything inconsistent with the age, mileage or history you have already reviewed.
Take a proper test drive
Where you are legally able to drive and appropriately insured, allow enough time to assess starting, steering, braking, transmission, suspension, warning lights and unusual noises. A data check is not a mechanical inspection.
Consider an independent inspection
For an expensive purchase, an older vehicle, or where the history gives you concerns, consider having the vehicle inspected by a suitably qualified independent professional before buying.
Resolve questions before paying
Do not let a deposit or collection deadline pressure you into ignoring unexplained information. Resolve material discrepancies and make sure you are satisfied with the vehicle, documents, seller and payment arrangements before money changes hands.
QUESTIONS TO ASK THE SELLER
Make the history do some work for you.
MOT issue“Has this been repaired, when was the work done, and can I see the invoice?”
Ownership“How long have you owned the car, and why are you selling it?”
Maintenance“What servicing or major maintenance has been carried out recently?”
Damage“Has the car had accident, body or paint repairs while you've owned it?”
Warning signs“Are there any faults, warning lights or repairs you know the car currently needs?”
BEFORE YOU PAY
Four things worth stopping for.
Identity does not match
Do not ignore differences between the physical car, registration, available VIN details, V5C and seller's explanation.
History is unexplained
A seller should be able to address important questions raised by the records. Evidence is more useful than a verbal assurance.
Provenance needs resolving
Outstanding finance, stolen or write-off information can materially change the buying decision and should be understood before payment.
You feel rushed
A deadline, deposit request or another supposed buyer is not a reason to skip checks you consider necessary.
USE THE VEHICLE'S OWN HISTORY
UKVEC turns records into questions for the viewing.
The checklist above works for any used car. UKVEC goes a step further by using the records returned for a specific registration to surface buyer signals and help you decide what deserves closer attention.
A clear history report does not guarantee the current mechanical condition, roadworthiness or suitability of a vehicle. Where appropriate, inspect the vehicle and seek independent professional advice.
