Buying a rental car is a tricky process as it can turn out to be a good deal or an expensive mistake. Although they are cheap, rental cars have an uncertain history, higher mileage, and lightly optioned. Since different people with different driving styles have access to the car, it is impossible to tell the driving history, which is the reason why most people will not buy a rental car. Furthermore, most car rental companies only buy the base models making it difficult to find luxury features and advanced safety equipment.
