I know you can do what you want.......BUT

A friend of mine who is really into Mustangs always has a Mustang or two that are of no particular interest to him. He buys them for an average price, cleans them up a bit, fixes a few glaring issues and then marks his selling price way up. His thought is, someone will always come along who wants one bad enough to pay what he's asking. Book prices don't get in the way of personal desire. So far he's been right, and he hasn't had to hang on to any for a long time either. He'll make a couple thousand and apply the profit to the cars he keeps.
