If you are looking to return your car to the dealership you purchased from, the first step is to get in touch with them. Many dealerships look to purchase used cars and the dealership may be interested in buying back the car. However, there is a good chance that you will not get back what you originally paid for it. The value of cars decreases over time and any depreciation will be accounted for when the dealership gives you an offer. Remember that if the dealership is offering you less than what you owe, you will still be responsible for paying the remainder of the loan.
