Wow - that's a small frame - I don't think it's bigg enough to be a 52cm!! Fit aside, it is a nice bike. I had one almost exactly like it (2100), except mine had standard drop bars and RSX STI shifters. You didn't mention what the likely "buy" price will be, but I bought my 2100 used, rode it for a whole summer, and sold it easily for $400 (bear in mind I live in a HOT bike market).

These bikes ride very well, and are still pretty popular. I see lots of them around. Things to consider would include the carbon tube/alloy lug joins. Some have reported the glue/bond coming loose or cracking, so that might be a concern.

Were I you, I'd prefer to inspect and test for fit before buying this bike, and if you're new to road cycling you will probably find the Scott aero "triathlon" configuration of the handlebars uncomfortable - which means additional expense to convert back to standard configuration. Something else to consider......
