It's quite possible, especially if his shop is Performance. He did say it was a display model and had a ding.

I got my '08 Roubaix for $630 new (shipped from warehouse to get right size, 100% virgin bike). It was on clearance + some other special they were running. It's equivalent to the Roubaix ACR of today, tiagra/105 components, carbon fork&seatstays, etc.
