Guides Selling

Selling privately, part exchange or an online car buyer?

The three main ways to sell a used car compared: how much you're likely to get, how much effort each takes, and the catches to look out for.

There's no single best way to sell a car. It's a trade-off between getting the most money and getting it done quickly with the least hassle. Here's how the three main options compare.

  Private sale Part exchange Online car buyer
Price Usually the highest Usually lower Usually lower
Effort Adverts, viewings, test drives Very little Little: online valuation and inspection
Speed Days to weeks When you buy your next car Often within days
Risk Time wasters and payment scams Low The offer can drop after inspection

Selling privately

You'll usually get the best price, because you're selling at close to the retail value rather than to someone who needs to make a profit. In return, you write the advert, answer messages, arrange viewings and test drives, and take payment safely. Follow our guide to selling your car.

Part exchange

The dealer takes your old car as part payment for your next one. It's quick and simple, and there's nothing to arrange. The catch is that the part exchange value is usually lower than a private sale, and a big discount on one side of the deal can be offset on the other. Ask for the price of the new car without a part exchange too, so you can compare.

Online car buying services

You enter the registration and details online and get an instant valuation, then the car is inspected at a branch or at your home before payment. It's fast and convenient. Be aware that the online figure isn't guaranteed: after the inspection the final offer can be lower, and some services charge fees. Get valuations from more than one, and don't feel pressured to accept on the day.

Getting the best price, whichever way you sell

  • Clean the car and fix small faults such as bulbs and wiper blades.
  • Have the service history, logbook (V5C) and both keys ready.
  • Know what similar cars are selling for, so you can tell a fair offer from a low one.
  • Clear any outstanding finance, or know the settlement figure, before you agree a sale.

Buyers like a clear history. Running a check on your own car shows them there's nothing hidden, and lets you deal with anything unexpected before they find it. Check your car.
