@Fab: I agree with you. I didn't say I'd necessarily trust him with my money, or that he has any experience in this, just that I don't think there's any evidence of anything illegal or fraudulent. I probably don't have much more than 10 eBay rating points, but I'd like to think I'm an honest guy.
I also agree he isn't painting the car in the best light in the way he's created the page and described the vehicle. People predisposed to dropping $200K on a whim are probably used to a little more refinement and polish
I think the charitable aspect is really quite clever - his goal is to get people to knowingly overpay for a product. If he can find a way to encourage people to do that (and to feel good about it) without any actual cost to himself, why not? Again, it's a Win-Win. eBay handles the charibable part; so I'm confident the charity would actually get their cut too.
