Step 1: Define your needs and budget

Start by deciding what type of vehicle fits your daily life, fuel preferences and how much you can spend. Include insurance, road tax and running costs in your budget to avoid surprises later.

Step 2: Search and shortlist

Browse reputable online marketplaces, local dealers and private listings. Write down each registration number, advertised mileage and any special features so you can compare them later.

Step 3: Verify the vehicle’s identity

Check that the registration number on the V5C (logbook) matches the number on the car, the number plates and the MOT certificate. Look for signs of tampering such as mismatched fonts or uneven rivets.

Step 4: Get a full history check

Before you meet the seller, run a comprehensive check on motorpeek.com. The report will show the DVLA‑recorded MOT history, any insurance write‑off categories (Cat A, B, S or N), PNC stolen or lost‑vehicle markers, outstanding finance, mileage discrepancies and the number of previous keepers.

Step 5: Inspect the MOT and service records

Ask to see the latest MOT certificate and any service book entries. Compare the recorded mileage with the odometer reading. A sudden jump of 10 000 miles or more may indicate clocking.

Step 6: Look for write‑off warnings

Insurance write‑offs are colour‑coded on the registration plate: red for Cat A, orange for Cat B, yellow for Cat S and blue for Cat N. A Cat A or B vehicle has been written off as a total loss and is usually unsuitable for road use. Cats S and N may be repairable but can have hidden structural damage.

Step 7: Check for finance and theft alerts

The PNC (Police National Computer) flag will appear in the motorpeek.com report if the car has been reported stolen, recovered or has an outstanding finance agreement. A vehicle with finance still attached can be repossessed by the lender after you buy it.

Step 8: Test drive and mechanical inspection

Take the car on a varied route – city streets, open road and, if possible, a short hill. Listen for unusual noises, feel for vibrations and test the brakes, steering and gearbox. If you are not confident, hire a qualified mechanic to perform a pre‑purchase inspection.

Step 9: Review the paperwork

Confirm the seller’s name matches the V5C, that the mileage on the logbook agrees with the odometer and that there are no blank pages or missing signatures. Ask for receipts of recent work, especially major repairs or part replacements.

Step 10: Finalise the purchase safely

Agree on a payment method that protects both parties – bank transfer or a sealed cash envelope is preferable to cash handed over in the street. Complete the change‑of‑ownership section on the V5C and send the seller’s part to the DVLA within 14 days.

Following this step‑by‑step checklist will help you avoid hidden problems and give you confidence that the car you are buying is genuine, road‑worthy and free of financial or legal encumbrances.

Frequently asked questions

What does a Cat N write‑off mean for a used car?

A Cat N (formerly ‘non‑structural’) indicates the vehicle was written off because of damage that does not affect its structural integrity, such as cosmetic or electrical faults. The car can be repaired and driven, but you should check the repair quality and obtain a full history report.

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

Compare the odometer reading with the mileage recorded in the MOT history, service book and any independent inspections. Large, unexplained jumps or a mileage that is lower than the recorded MOT mileage are strong indicators of clocking.

Is a vehicle with an outstanding finance agreement safe to buy?

No. If the previous owner still owes money on the car, the lender can repossess it even after you have paid the seller. A motorpeek.com finance check will reveal any active agreements, allowing you to avoid the risk.
