I'll ask you one thing. Which state are you from? The warranty still exists doesn't it?The lemon law usually applies to new cars bought from the dealer. If its "AS IS" there isn't much you can do. But, if not take action BEFORE the warranty passes. Right now these six states hold the used car lemon law in book: Connecticut, Massachusetts, Minnesota, New Jersey, New Mexico and New York. Even then, check with an attorney who would be able to give you much better advice as to how to proceed. This might help you. http://www.yourlemonlawrights.com/
