I don't practice in PA but, generally speaking, there is no "cooling off" period or changing your mind for entering into a legal contract for buying a car. There may be situations involving lemon laws or fraud, but those are based on facts supporting those situations. A PA lawyer can confirm.
I am not your lawyer unless we enter into an engagement agreement in writing. This is general information that is given for legal education only. It is not legal advice, and it may not work for your specific situation. I strongly encourage you to consult with a local lawyer to get legal advice and help with your specific situation at your earliest convenience. I am licensed to practice law in Arizona.
If you signed a no return contract, the terms are probably very clear that you can't return the car. Consider going back to the dealership and forthrightly tell them your problem before you put many miles on the car. They may be willing to work something out.
Likely. Always a horrible idea to finance a depreciable object such as a car. If you have $1000, you but a $1000 car, you do NOT put it down on a $20,000 car.
