You have a very nice one there. It does look NOS. A bit small in size (52cm?) but still a size that many C&V collectors/riders out there will fit into. The very new looking Mavic Clincher wheelset certainly helps to pull in more buyers, plus the very nice and new condition high line Campy components is always a big plus.
I can see an enthusiastic bidder paying around $800+/- for the bike and maybe a bit more if you get a bidding war going between a few guys that are big fans aluminum Alans/Guerciottis. It can easily sell for more if the C&V bike market isn't so depressed because of the recession.
As I noted, a similar condition CF version might get a bit more as CF construction just gives it just a little bit more of an exotic boost.
Good luck if you decide to go ahead and sell it.
