The majority of new cars that are not bought are either leased or used as dealer inventory. Leasing is when a customer pays to use a car for a set period of time, typically two to four years, and then returns the car to the dealership. The dealership can then lease the car to another customer or sell it as used. Dealer inventory cars are new cars that are owned by the dealership and used to sell to customers. These cars are usually sold at a higher price than used cars because they are new; however, they may have more mileage because they were driven by employees or customers who test drove them.
