A bike that goes for $1500-3000 on ebay, and routinely is listed for 2000-4000 on ebay, all for $500? Clearly, you've found a true bargain - better snap it up quick!
C'mon, man. You know the answer. You want the fantasy to be true, and you desperately want someone here to tell you "hey, this might be legit". Given that the pics appear to be from a bike that was just sold on ebay (see
here), and was listed as being in Vancouver, BC, I think you might be disappointed if you send the "seller" your personal information. I mean, really, who would move from Vancouver to Omaha? Is that even remotely credible?
You should flag this on CL.
