First, you mean a Miata. Don't refer to cars by their production code, it sounds retarded.
Secondly, they're pretty good cars. One of my friends had one, and I was rather surprised by how well it drove, and handled. If you're a big guy, it's not recommended. He was 6'2, and his head stuck up over the windshield.
I'm 5'9, and fit alright.
Other than that, nothing amazing to say about them one way or another.
