Looking to pick up my first roadie. I found a Cannondale Caad3 Saeco, I think 1999. Seller is asking $500 I'm going to try to work him down to about $400 is this still too much? Bike looks like it has Dura Ace and Tiagra, and frame is in perfect shape. He has upgraded the wheelset to Mavics, he hasn't told me specific models. Any words?
