A used-car buying checklist built around documents and questions

Before travelling: check the vehicle, not the advert alone

GOV.UK recommends asking the seller for the registration number, make, model and MOT test number before seeing a used vehicle. Compare the information provided with the official DVLA details, check MOT status and history, and look for relevant safety recalls. Open the services yourself rather than relying exclusively on images supplied in a message.

Read several test entries, not just the newest pass. Note recurring defect wording and any unexpected reading change. If the current status, vehicle details or documentary history conflict with the advert, ask for clarification before spending time travelling. A seller’s willingness to discuss the discrepancy does not itself establish that the explanation is correct.

At the viewing: compare identities and documents

The official used-vehicle guidance says to ask to see the V5C log book, examine its security details and make sure the vehicle information matches what you were given. It also directs buyers to compare the vehicle identification number and engine number with the log book. Follow the current official checklist for suspicious document details rather than relying on a remembered summary.

Ask for service and repair documents that relate to this vehicle and relevant dates. An invoice for suspension work may help explain a historic failure, but it does not answer every question about the current suspension. If documents are unavailable, record that limitation honestly rather than filling the gap with an assumed repair.

• Bring the exact advisory or failure wording you want explained.
• Keep separate notes for document checks and physical-condition questions.
• Do not send somebody else’s identity documents through our site enquiry form.

Arrange checks outside the MOT’s scope

An MOT does not settle outstanding finance, prove ownership, establish a vehicle’s complete accident history or provide a detailed engine and gearbox assessment. For an electric car, it is not a battery-capacity report. Decide which separate documentary checks and suitable inspections you need before committing, and understand what each provider’s report actually covers.

Do not turn an advisory list into a repair budget by guessing. Ask a qualified garage to inspect the relevant components and provide a scoped quotation. Similarly, our timeline does not estimate market value or show what a seller should accept. It only organises the dates and readings you supply so you can ask more focused questions.

Before committing: close the outstanding questions

Recheck current official MOT status near the proposed collection rather than treating an earlier check as permanently current. If a mileage discrepancy, unexplained gap or serious condition question remains unresolved, pause. A clean-looking timeline and friendly explanation do not remove uncertainty. Retain the records and written answers relevant to your decision.

GOV.UK says to tax the vehicle immediately if you buy it, using the green new-keeper slip from the log book. Its buying journey also covers registering the vehicle and arranging insurance. Those steps are separate from reading the MOT history; a valid certificate is not the whole permission-to-drive question. The official sources behind this checklist were checked on 6 November 2026.
