Buying a car

Buying a used car – know your rights and stay informed

Buying a used car can be a big investment – make sure you protect yourself by doing the right checks and understanding your rights.

Top tips before you buy

Choose a reputable seller

Ask friends or family for recommendations.

Check if the dealer is part of a trader approval scheme or trade association (e.g. The Motor Ombudsman) and confirm membership with the relevant organisation.

Check the car’s history

Use free tools on GOV.UK to check:

  • MOT history
  • mileage
  • if the car has been written off, stolen, or has outstanding finance

Match the VIN (vehicle identification number) and engine number with the logbook (V5C).

Inspect before you buy

  • examine the car in daylight and dry weather, if possible
  • take someone with experience or consider a professional inspection
  • review documents: logbook, service history, MOTs

Warranties & Guarantees

A warranty does not replace your legal rights.

Check what's covered, how to claim, and any conditions that may void it.

Always ask to see the warranty in writing before agreeing to buy.

Before you sign

Before finalising the deal, ask:

  • what checks have been carried out (mechanical, mileage, accident history)
  • has the car been used as a taxi, rental, or previously written off?
  • are there modifications from the original spec?
  • what after-sales support is provided?

The deal

Confirm the "on-the-road" price includes VAT, number plates, delivery, and tax.

If part-exchanging, check your car’s value online.

Understand any finance agreements: interest, repayments, deposit terms, and cancellation rights.
