rear shocks
rear upper shock mounts
tranny upgrades(1-2 accum/Mercon V)
air suspension(typical life span-10 yrs/100k)
warped front brake rotors(steering wobble under braking)
idler pulley/tensioner
probably needs a full tune-up(plugs/wires/fuel filter/pcv)
wiring loom/connector in trunk at L/S trunk hinge.
outside door handle(s)
trunk mounted CD changer(if equipped) might act up
guess what? every car out there has its quirks. No matter what, it is going to need *something*...I would take a good long test drive(get some heat into the tranny) and notice all the GOOD things. You know you already want it...now go drive the snot out of it. Also, check the paint's clear coat...especially on the "top" surfaces of the roof/hood/trunk/bumpers for fading/oxidizing. Also, find out as much about the car's maintenance history as you can, as well as try to get an over-all feel of how well the car was taken care of. Press the buttons on the message center to see AVG MPG, and put it through the SYSTEM CHECK.
Good luck.
