This is also posted on the Cervelo forum. I am hoping for a broader and more impartial response here.

I am looking for some input as to the resale value of a 2002 Cervelo Prodigy (white with nickel stays). They don't come up on Ebay very often so that has not been a useful resource for establishing a price. I have 2 of them that I would like to sell, one is a 56cm, the other is a 50cm. Both have their original Campy Centaur 10-spd with an upgrade to Chorus shifters when purchased new. The 56cm has OpenPro rims on Centaur hubs (36r/32f). The 50cm has '02 Campy Proton wheels. Both are in very good condition and have been well maintained. Any advice is greatly appreciated.
