Right up to the moment the contract is signed.
A lot of people believe that you have some time to "change your mind" when you buy a new car (some of them believe this adamantly and rather stridently); however, this is not, in general, true in any state in the US. (Most states do have some kind of "cooling-off period" required on certain types of sales such as those made by door-to-door salespeople, but car sales are typically excluded from this either explicitly or because nobody goes door-to-door trying to sell cars.) Some states do require that buyers be offered this as an optional add-on for new car purchase contracts, but the dealer is allowed to charge extra for this, and if your contract doesn't explicitly say that you have X amount of time to change your mind, then you don't.
Note that even though the state does not force a dealer to allow you to back out of a contract, the dealer can choose to allow you to do so anyway. You can always ask.
No, a dealer cannot change the contract after it has been signed.
No, a car dealership cannot change your contract after it has been signed. Once a contract is signed, it is legally binding and cannot be altered without the consent of both parties.
Yes, the contract has been performed even though it has not been signed.
That depends on whether you have signed a contract with the buyer.
A contract can be amended after it has been signed by creating a written document that outlines the changes agreed upon by all parties involved. This document, known as an amendment or addendum, must be signed by all parties to the original contract to be legally binding.
