This turned up on CL this morning...
I checked the Bianch USA archives and can't ID what year or model it is, so I'm turning to the experts. My next question would be, is it a $700 bike? I can get a brand new Volpe for not too much more than that. I'm going to email the seller to try and take a look at it this afternoon after work, so I'd love to be informed when I go.
Thanks for your help!
edit: the closest I found was the 2001 Volpe, but I don't know if it came in Celeste that year.
