I'm pretty sure, that if you agreed to the deal, he wouldn't really send you a wire. He'd send you a faked scan of confirmation of sending a wire, and try to make you release the goods based just on that fake JPG/PDF or something like that. A wire would never appear on your account.
Excellent call. But that doesn't change the fact that I clearly remember reading about this very technique on a car auction site. Belgian car auction sites warn for foreign money transfers to this day, though they don't clearly state why. But please, as I've said several times already, I'm merely reproducing info that I
read on some anti-fraud site a couple of years ago. What you think of it, well that's up to you.
