Have you ever just asked if its for sale??

I get sick of the a--holes that ask me if my 68 Barracuda fastback 340-S is for sale and then try to offer only $500 or $1000... WTF??? Are you kidding me?
worse than that (well, almost as bad) is the people who say "if you ever want to sell it, let me know" and then when you decide to sell it, they aren't interested.
