According to the Federal Trade Commission, auto dealerships are not legally obligated to give preowned car buyers a three-day right to cancel their purchase. This means a sale is final once a preowned vehicle buyer signs all of the necessary documents. However, some dealerships do offer a return policy, though that offer will likely not be made unless the buyer inquires about it. When a dealer does provide the privilege of returning the vehicle in 72 hours, the policy may be referred to as a “money-back guarantee” or a “no questions asked return policy.” While many dealers are trustworthy and willing to work with their prospective customers, the FTC recommends all buyers contact their local consumer protection agency and state attorney general to determine if there are any unresolved complaints on file with regard to a particular auto dealer. This can help buyers find a reputable dealer and give the buyers some additional peace of mind, especially for those shopping forpreowned vehicles that tend to carry more risk than a brand new car.
