What Car Should I Buy?

Yeah, that's what I thought. I just don't see how it's supposed to work on fleabay - as I understand the rules, if you bid and win, you're basically tied into buying the damn thing. It doesn't seem right that you'd just bid and buy a car without ever seeing it or driving it first, so I must be misunderstanding some crucial part of the process.

I know this is how ebay works - you bid and buy.. but if you're not paypalling and planning on paying cash, is there anything to stop you just walking away (apart from slightly bad feedback perhaps?).
I've walked away from a Bianchi once I saw it and nothing happened. I can't imagine you'd face any consequences worse than spending a grand on a lemon.
