2002 celica gts is this woth it

Hi im looking into buying a red 2002 celica gts the thing is it has 86000 miles on it and he's only selling it for 8500. The only thing that i could see was wrong with it was some paint oxidation atleast from a glance . I plan to do a test drive but still the bluebook value makes it worth more than 8500 . SO I would like to know if this seems like a good deal or does it seem fishy to anyone else .Also what should i be looking out for to make sure everything is cherry when I take that test drive.
