Hello Trimadsco welcome to the forums. I am pretty sure that is an '89 model year because of the Suntour GPX. steel Bianchis have a great following and this being in such good shape will sell quickly depending on where you live, and your location also effects price. there is a an actual forum here for apprasails but I would say if you coulkd air up the tires and ride that it would sell for about $200 to 250 as it sits.
