Top tips

Before approaching the dealer for a part exchange value, check your car value through car valuation guides such as Parkers, CAP, and Glass's. It is the trade value that the dealership will offer.

Often dealerships will give less discount on a new car if they need to factor in a part exchange. This allows them to add more value to the part exchange price. It may be worth discussing the new car price first before requesting a price for your part exchange. This will give a clearer view on how much you are receiving for your current vehicle.
