Is the guy a friend? Have you let him know that you Need your money? If one of my local Supra friends needs something to make his car go, he is more than welcome to come get it if I have an extra, and pay me when he can. I actually have this situation right now. The guys turbo went out and I let him come get it, and he paid me half what I wanted, and I told him to get me the other half when he can. He soon lost his job, and it has been almost 6 months. He's a buddy, I'm not pissed at all. Someone else on this board that I consider a good friend gave me a fantastic deal on the turbo I have now. Every situation is different. If you are not happy, let him know it. If he does not respond to that, start a dispute. But, be warned, if he was a friend, that may be the reason that friendship changes.
