Perhaps as the guy is getting older he just wants to do small repair jobs.
I can understand that. But I don't know why he doesn't just tell you that now. There may also be some personal stability issues behind having to change business locations so many times.
I hope he doesn't have any of your cars or parts. If not, I think you just have to forget about it. Whatever it is, his wife is running interference for him.

P.S. Want to sell the flywheel?
