I had a 2000 Special Edition MX5, miss that car very much. I love my FiST, but my Miata was the most fun car I owned, albeit the least practical.
I am really on the fence right now. Part of me wants to keep the FiST, a car which can hold my entire family and is fun to drive. The other part of me wants to sell the FiST next year, and upgrade the wife's vehicle to something a little bigger and newer ('11 or so Expedition EL) and get another Miata for my DD and our date car. Ideally, a Miata would be a third, fun car for me, but not in the budget or practical at all since I'm active duty and we move every 3-4 years.
If I got another Miata, it would be 97ish or another 2000SE, and I would do a decent amount of work to it.
