It's his loss. I've purchased and sold a number of cars and the "deposit" rule is more set than the "keep at least one urinal between you and the next guy over" rule. The fact that he changed his mind doesn't mean he gets his deposit back ... it means he forfeits it. Like someone else said, the deposit is to prevent you from selling the car to anyone else. If he changes his mind, than it's your right to keep the deposit for compensation since you lost potential buyers and therefore potential money during the time that he was "thinking" about it. Now, if you ahve a nice fat steady income and don't need the $$, than I'd give it back - because that's just being stingy to some kid trying to buy a car. However, if money is tight (like mine) than you've absolutely got the right to keep that $$.
