Value thoughts? Specialized Transition Comp

Listed for $900. I was looking for a new bike in the $700 range so offered seller that and he said best he can do is $800. Hopeful I could get him down to $700 if no one else is interested in it, but really curious about what yall would consider a fair price for this bike. My best guess is that it was a 2008 or 2009 but not totally sure.
