I had a 90 from 94-00, and then I had a 99 from 03-06. I liked the feel of the 90 better than the 99, although the 99 was more refined. Bought my 04 S about 5 months ago, and I am having a great time.
I've owned a Miata since 1991. My current Miata is a Mega-Monster V8 with a KB supercharger. It is for sale if anyone wants 430HP and 461TQ. I'm getting too old to handle it, 67 in August.
