How can I "But" it? And should I?

I was trawling around eBay and found this listing.

Specialized S-Works Epic FSR 29er Carbon Full-Suspension Mountain Bike 21.2lbs!!

The photograph accompanying the listing looked a bit too professional for your usual eBay listing.

When I looked, the price for the auction was just over $700 dollars, a killer deal, but something about this just looked fishy. 

The next part of the listing was the "nail in the coffin".

You know, I've always wanted to "But it Now".

This may have been on the up and up, but something about this just did not seem quite right. $2350 would be a amazing deal for a bicycle that usually retailer almost $10,000. But if something seems too good to be true, then it usually is.

I followed up with the vendor and was informed that the frame size is 54 centimetres. This was another red flag as that would be a massive frame for a mountain bike, and does not fit at all with the photo.I checked on the Specialized website and the largest frame (XL) is 52 centimetres. I asked about the make and model of the components and received no reply.

Something, well pretty much everything, about this auction, does not seem quite right. I won't be bidding.

Postscript: The auction disappeared and I never did hear back from the vendor. I guess if something looks to good to be true it usually is.
