Not trying to be bias, but I have to say 92 -95.
Reason? My '93 reminds me of a throw back to an old car from the mid 60'* and early '70'*. The rear lights remind me of an old Plymouth Fury, and the rest of the body reminds me of a muscle car. I think this era of Bonneville was the original immitation of great cars from the past. The frowning headlights remind me of my brother'* 1970 Super Bee, very menacing! It just looks like a beast, and I think it scares the young and elderly.
The lines are appealing too. Oh, I want to run out and hug my car right now!!!
