Trading cars can be seen as a service. At the time of delivering your new car, the service of car trading will prevent that you have a second car over which you need to pay insurance money and road tax. Furthermore, the private sale of a car can lead to the selling party being held liable for subsequent deficiencies. It may also happen that the price asked isn’t paid after all and that insurance and road tax will have to be paid over a longer time. Plus, most people aren’t keen on strangers at their door for the sale of a car. If these discomforts are taken for granted, then private selling can sometimes yield higher prices and mostly, car companies grant a discount on an occasion when there’s no trade-in car. That’s why trade-in prices of occasions are often higher then regular sales prices of the same model on the Internet. The car company needs to check the car and supply it with a warranty, next to the possible risk of not being able to sell the car.
