I purchased my '93 2.3 new in Feb. of 1993. It currently has 89,700 miles.
Here are some things I have had to replace, besides normal maintenance like brakes, rotors, belts, hoses, etc.
Values will be all over the board, from a few hundred dollars to $6,000 or so.
Belt tensioner, 2 times.
Struts and shocks.
Coolant temp. sensors.
Aux. fan relay.
Water pump.
Shifter bushings.
Vacuum Modulator.
Engine mounts, front and rear.
Radiator, due to weak plastic upper hose connection.
Tie rods.
Steering damper.
AC compressor at 84,000 miles.
Head gasket and associated parts at 87,000 miles.
The car runs and drives great and gets around 20mpg city and 25mpg hwy.
