Car Deposit Refundable?

I was a car salesman and you dont know what you are talking about in regards to a deposit at a dealer. When buying a car 15% is not needed!! All you have to do is write a letter stating you need your deposit back dude to hardships. Since they havent put the car in your name they havent processed the paper work as yet. IF they still give you a hard time after that, get BBB involved. They will give the money back. LEGALLY there was NO damages done and they cannot put force you to buy a car you dont want to buy. DONT SIGN anymore papers!! call me and I will explain it better than online.
