Some of them are not satisfied with the performance of the vehicle. I met a case where my husband bought a car for his wife and chose lexus ES200. As a result, my wife used it for a while and felt that the motivation was too poor. She wanted to change cars and sold her new car for several months. This situation is not uncommon in quasi-new cars. Or not long after buying a car, something happens at home and you need money to sell it. This is a lot of cases, otherwise no one can buy a new car for a long time, after all, you will lose a lot of money.
