I always think when something like this bike is listed, the seller is trying to pull one over on the buyer, the reasons for my distrust are largely when you get photos that are blurred, there simply isnt any reason for this nowadays with the technology of digital cameras, i would be thinking they are trying to mask out any imperfections in the paint work, scratches, rust, dents etc...

Also apart from knowing that youre getting cinelli bars and a brooks saddle you dont know much about the bike by reading the ad.

In summary Id say only buy this bike, if you can identify from the photos the parts on the bike, or are able to arrange with the seller to view the bike, this way you would avoid any nasty suprises, also make sure that the bike is genuine, by trying to find reference to the model, find old catalogues on the net/ see if anything similar exists, and what it sold for.

Value of old bicycles is very much a case of whatever the buyer is willing to pay, im not sure of the model myself so cant advise
