I had 2 XXs, both `97s. 1997 and 1998 were exactly the same, only the VIN plate changed - same color, everything. 1999 introduced a change with FI and some minor body changes - still same color. After 2000, all I can remember is changes to color, maybe an instrument/dash update?
So, only 2 versions of the XX - carbureted and fuel-injected.
