How to Buy a Car Online in the UK

Everything you need to know before buying a used car — from setting a budget to handing over your money safely.

1 Set Your Budget

Before browsing, decide your maximum spend including insurance, tax, MOT, and running costs.

  • Under £3,000 — older, higher-mileage cars. Budget for potential repairs.
  • £3,000–£8,000 — solid used market. Most reliable options for first-time buyers.
  • £8,000+ — newer cars, lower mileage, often with remaining manufacturer warranty.

2 Choose the Right Car

Think about how you'll use it daily:

  • City driving — small hatchbacks are easiest to park and cheapest to insure.
  • Family use — estates or MPVs give more boot and passenger space.
  • Long commutes — diesels or hybrids are more economical at speed.
  • First car — look for cars in insurance group 1–10 to keep premiums low.

3 Check the Car's History

Before viewing any car, run a history check using the registration plate:

  • MOT history — check previous results and advisory notes at check-mot-history.service.gov.uk.
  • Outstanding finance — a HPI check reveals if money is owed. The finance company can repossess even after you've paid.
  • Written-off status — Cat S and N write-offs can be sold legally but should be priced lower.
  • Mileage discrepancy — compare listed mileage against previous MOT readings.

4 View the Car in Person

Never buy without seeing it. At the viewing:

  • View in daylight — much easier to spot bodywork issues.
  • Check for uneven panel gaps, mismatched paint, or signs of accident repairs.
  • Look underneath for rust, especially on sills and wheel arches.
  • Start the engine from cold — listen for rattles, smoke, or unusual smells.
  • Test all electrics: windows, heating, infotainment, lights.
  • Take it for a test drive on a variety of road types.

5 Negotiate the Price

Most private sellers expect negotiation. Use MOT advisories, worn tyres, or minor dents to justify a lower offer. Research what similar cars sell for on AllCars first. A reasonable starting offer is 5–10% below asking price.

6 Pay Safely

  • Bank transfer — traceable, but only transfer once you have the V5C logbook in hand.
  • Cash — bring exact amount, get a signed receipt.
  • Never pay a deposit to reserve a car you haven't seen.
  • Avoid PayPal Friends & Family or cryptocurrency — no buyer protection.

7 Complete the Paperwork

  • Get the V5C logbook — seller sends the main section to DVLA, you keep the yellow slip.
  • Notify DVLA at gov.uk/change-vehicle-keeper.
  • Sort insurance before driving away — driving without insurance is illegal.
  • Road tax does not transfer with the car — check it's valid or arrange your own.
