Some states have "Lemon Law". Meaning if you get a crap deal with a car, you may be able to get ALL your money back. But I think you have to prove they knew it was bad. Sounds to me (I am NOT a lawyer or have really anything to do with the law. Just watch WAY too many "judge shows") they might have known. That and with the car breaking down the NEXT day, you may win here.
My suggestion, contact PFB and get this pulled (it could come back and hurt you) and contact a lawyer. Check in to the Lemon Laws. Good luck!
