No drive side pic but the bike looks clean. Asking price on this is $500 on St. Louis CL. $500 is a little high for this bike.

Assuming the bike is stock, it has a campy crank and derailleurs, modolo brakes, stronglight A 9 headset (great headset), sunshine hubs, matrix rims. The frame is Reynolds 531 CS.

I doubt you'll get the seller to move on the price given what is written in the ad and you are unlikely to find a bike in as good a condition as this assuming it checks out. If you like it and it fits you, this is a reasonable price even if you might be able to do "better" if you shop around.
