There is no 3 day buyer's remorse grace period for you to return the car after buying it

There is no "undo button" when you buy a car. You buy it, the deal is done. There is no 3 day grace period to return your car, although many people erroneously think there is one. You should not continue to shop for cars after you buy your car and expect the dealer to take the car back, just because you found it cheaper later on. It's unethical and not the way to do business. We get emails about this all the time, and just delete them.
