I have both a 92 and a 93 ls with the air suspension option. On the 92, if you look at the dash there are 3 indicators. Lo Norm Hi. On the 93 there are only 2 indicators which are Norm Hi. I like the fact that when I am driving in the 92 when I hit faster speeds the car lowers and the display changes to Lo inside the cabin to alert me. I was wondering why this was changed in the 93 model. According to the book, the car still changes to the lower mode with faster speeds but there is no disply in the cabing telling me this. I'm sure this sounds like a dumb question, but it is something that not even the dealer can answer and i was just curious.
