if the 120k maintenance isnt done, that will need to be soon (yes toyluver said this. making sure you know). o2s could use replacing if not already, as well as the pcv valves. clutch good or not? brakes ok? batery/alternator/electrical system check out ok? COMPRESSION TEST!!! get one before or right after the test drive (drive it to get one. 2 birds with 1 stone). springs sagging? shocks ok? general suspension? and pretty much anything else a normal car of that mileage needs checking
