Well, for one thing - it doesn't have any rattles, shakes, or shimmies of unknown origin and anything of that nature!
The more I drive it, the more details that I find that I like about it.
It's taking me a little while to get used to the 6 spd, vs the 5 spd that I'm used to driving. First does wind out nicely without being too short of a gear. The shift points are different and in certain situations I find myself shifting alot between 2nd and 3rd. But, it is a hoot to drive. Feels really solid - the body is ALOT stiffer than my 1990 was even after adding strut tower brace, rollbar and other braces under the body. Most surprising thing is the amount of body roll in the corners. Alot more than I'm used to and I even have the upgraded suspension package. Eventually I'll probably go with lowering it a little and with stiffer springs. At first I hated the plastic sun visors, then I realized that they recess into the top of the windshield and don't get in your field of vision like the ones on my old miata. I find the interior driving position extremely comfortable. You can just jump in and drive! Somehow it is very reminiscent of my old 1991, but it's a hell of alot faster!
