Frequently asked questions

What does part exchange mean?

Part exchange refers to a transaction in which part of the cost of the car you intend to buy is covered by a car that you already have in your possession. You trade in your own car as a part payment for the car you’re buying. The value of your existing car helps reduce the cost of the new car.

How does part exchange work?

When you submit your REG number and mileage of your car, we will generate two quotes for you. One is your instant cash offer, which is how much you would get for just selling your car. Next to it, we will show you your part exchange offer, which is how much you would get for your vehicle in a part exchange deal. This offer can be up to £1,000 higher than your instant cash offer and it is used to offset the price of the new car you are looking at. For example, you might trade a 2017 BMW 5 Series as part of a deal to purchase a 2021 BMW 5 Series, offsetting the cost by several thousand pounds.
