Some people on here are incorrect. Depending on the state the vehicle was purchased in, Lemon Laws do very often cover used cars. The problem is to win in court, you must prove the dealership lied to you about the condition of the car, and that is very hard to do. If you specifically asked if the car had ever been in an accident and they said no (and you have an email or something to prove it), you are as good as gold. But with any lemon law, you must first give the dealership the option to refund your money or repair the vehicle. Anyway, make sure you have all your paperwork in order, check the lemon laws of the state in which the car was purchased, and print out a copy of the original ebay ad and any correspondence you had with the dealership. You may be better off simply allowing a local dealership to repair the problems if the car is still under warranty and can be fixed for free.
