The prospective buyer must be given the registration certificate and all keys during the hand over. Loose items, such as the car's instruction manual, equally need to be transferred to the new owner (unless you have indicated in the description that these are missing). Once tyou receive payment for the vehicle, all registration documents, keys and manauls are exchanged to the new owner. It could not be simpler or more straightforward. Our 70.000 + dealers also ensure that you get the optimal price for your company car.
