As several people mentioned, there are two things going on here. The OP's Pinarello was a repaint, with chrome painted over, and listed with poor quality photos. When I see a frame with painted over chrome, I assume the bike has had a tough life and the chrome was beyond salvation. Poor flash photos made it hard to distinguish paint chips and reflections. This presentation makes potential bidders assume the worst.

The Pinarello in the link is a more recent frame, with original paint and excellent chrome. While the pictures were again poor quality, everything they showed looked very good. That's what it takes to create the "i gotta have it" emotion for the prospective bidders.
