Significant / or Insignificant changes:
91- front bumper and side molding, wheels, size of cutout in windshield
92- traction control, emblems added to side of hood, exhaust tips
93- wheels, 40th Edition, 405 horsepower, but car got heavier, PKE Remote
94- SEATS!!! Lear!!! White lettering on controls, wheels
95- many with 2 Dunn heads, shifter, reverse lockout change
Likely missed some!
I would not get "hung-up" over the changes.
All years are great!
Changes are actually minor, evolutionary, not revolutionary.
