I own and drive a 1988, 89 and 90. The '90 is without the CRT but has the more modern dash look. But as we have seen the CRT has made a comeback and is on most cars today. So the '90 is actually more "dated" then the '88/89. The '88 has the black horn button and suede seats [both out of the car and replaced with standard seats and sunburst horn button so looks like the '89 other then what Ronnie said about the glove box and keyless entry.
Because the '89 is my "first" and Red [my preferred color] it is my favorite.
