Can you return a car after sign the papers if dealer says he made mistake and give it to for price signed for?

In most cases, no, you cannot return the car after you have signed the papers if the dealer claims they made a mistake. When you sign the purchase agreement for a car, you enter into a legally binding contract with the dealership. This contract states that you agree to buy the car at the agreed-upon price and that the dealership agrees to sell it to you. Once the contract is signed, it is generally not possible to cancel or return the car, even if the dealer made a mistake.

However, there may be some exceptions to this rule. For example, some states have laws that give buyers a certain amount of time after purchasing a car to cancel the contract and return the vehicle. These laws are known as "cooling-off periods." If you live in a state with a cooling-off period, you may be able to return the car within the specified time frame if the dealer made a mistake.

To find out if your state has a cooling-off period for car purchases, you can contact your state's attorney general's office or consumer protection agency. You can also check the Federal Trade Commission's website for information about consumer rights when purchasing a car.

If you are considering returning a car after signing the papers, it is important to talk to a lawyer first to discuss your rights and options.
