Exterior:
-side mirrors from 94-96 are different from 97-01
-front and rear bumpers are different from 94-97 vs 98-01
-headlight assemblies and turn signals are different from 94-97 vs 98-01
-steering wheel " "
-a/c display " "
-in 94-97 you can open the hatch from inside with a lever, 98-01 forgetaboutit because there's a latch from the outside located on the hatch itself
-94-97 mostly had the door moldings unpainted and all were black but most 98-01's have the moldings painted the same color as the car
-94-97 tails have the amber part in the lense, 98-01 are all red
That's all I can think of.
