Undecided.... sell it or not

I would be pissed off if somebody told me that they were selling and agreed on the price and changed their minds....that why I'm asking...and appreciate your response, but I also believe that he's got to have the money in hands for me to think he's real serious..like I said for two years he's been asking but never with money showing...his father passed away, now I know he's a little more serious for having it.... I'm not selling it because I need to pay anything and I do have another car to enjoy but I think I'd miss this one if I let it go.
