There is no buyer’s remorse, cooling-off, or right-to-rescind law that requires the seller of a new or used car to cancel the sale or accept the return of the car. When you sign the contract for the purchase or lease of the car, you are legally obligated to the purchase or lease. Because of the finality of the lease or purchase agreement, it is important to carefully read and understand the agreement before you sign it—and to determine whether buying or leasing the car is a good financial decision for you. Some state laws require car dealers to offer extra protections for buyers of used cars—such as a contract cancellation option agreement that the buyer may purchase for an additional fee, and that will allow the buyer to return the car and cancel the contract within a short period of time (2 days).

In South Carolina, there is no specific buyer's remorse or cooling-off period law that allows a buyer to cancel a car purchase or lease once the contract has been signed. Once you sign a contract to buy or lease a car in South Carolina, you are legally bound to that agreement. It is crucial to thoroughly review and understand the terms of the contract before signing it. South Carolina does not mandate car dealers to offer a contract cancellation option for used cars. However, some dealers may voluntarily offer such options, but these are not required by state law. Buyers should inquire about any return policies or contract cancellation options before finalizing the purchase, but should be aware that these are not guaranteed rights under South Carolina law.
