I screwed up!! Advice please?

Well Guys, I went down this road before regarding cars not being what they're supposed to be. Unless you have a contract document saying otherwise an "as is" sale is just that, "as is" . Even if you can prove fraud you'll have a hard time getting your money back and you'll spend more than the price of the car going to court. So from experience I'd say "suck it up" and spend the money you would spend chasing this guy on parts to fix you car.
