If you purchase a new vehicle and then no longer want the vehicle can you return it to the dealership and rescind the contract?

If you purchase a new vehicle and then no longer want the vehicle can you return it to the dealership and rescind the contract?
The immediate answer to the question is, NO. I am not aware of any State that has laws that allow this. Some States have Lemon Laws for used cars, but I'm not familiar with anything for new cars. Some dealerships may offer a "money back" policy if you are not satisfied.

If you do not pickup the new car from the dealership and want to recind the sales contract, can you cancel the contract if only one spouse signed for it/ Doesn't it take both people to sign the contract if both names are on the registration?
If you live in California and you sign any contract, you will be unable to return the vehicle. In a rare case, I practically begged the manager of a used car lot to unwind the deal. I told him that my wife purchased a car for me prior to my purchase of their car, but I was completely unaware of it. They finally let me out, but withheld a $40.00 documentation fee and a 2.9% credit card surcharge. $178.00 is better than a $6000 used car that I decided that I didn't want. Also, when I purchased the car, I left it at the car lot and told them that I'll pick it up in a matter of days. I guess the unwinding of the deal helped for the simple fact that the car never left the lot and I came back the next morning. It only took me one night to think about the deal and realize that I wanted out. The most important thing is to not let the sales person pressure you into signing anything. Don't listen to 'this car may be gone tomorrow,' 'this is as low as I can go,' 'you will not find a deal better,' etc. It's all bull. It will get you in trouble if you sign the contracts, but you later want out. THERE IS NO WAY OUT AND THERE IS NOTHING THAT YOU CAN DO ABOUT IT. Everything is monitored and recorded from the minute you step on the car lot until you go to the back office to sign the 'nail in the coffin' contracts. Before you sign anything, go home and think about it. It will save you a lot of headaches. DON'T SIGN ANY CONTRACTS UNTIL YOU ARE COMPLETELY HAPPY WITH THE CAR! If you already have and you want out, the best advice that I can give is make up any good believable heartbreaking lie such as: Someone passed in my family and I need the money to help fund the burial expenses, etc. Go in the office crying if you have to. It may work, but it may not. YOU WILL BE CRYING FOR REAL IF YOU ARE UNABLE TO UNWIND THE DEAL. The best time to put on an act is when a sales person is with a potential car buyer. The car lot or dealership people most likely won't show their true colors in front of potential car buyers. They'll put on an act and most likely, unwind the deal. But again, this is rare, like in my case. DON'T SIGN ANY CONTRACTS UNTIL YOU ARE COMPLETELY HAPPY WITH THE CAR!
