The title pretty much says it all. A good friend (really is a friend) of mine bought a used car in the state of Florida from a dealership yesterday and wants to back out. He paid no deposit, but did sign a purchase order.The car itself was less than 4k, but the dealer tacked on an additional $699 as a dealers fee, and amongst other things, the price of the car ballooned to $5500 after TTL.I realize that there is no cooling off period in Florida, and that the dealer can sue him for his assets. He is a student and has no assets to speak of. What are the chances of the dealer actually doing that? He wants to shop for a less expensive car, but don't want this to come back to haunt him down the road.Any insights would be appreciated.
