It's a good car. Extremely nimble in skilled hands. Can be "legoed" almost as much as an AR. Also with it's balance and excellent suspension straight from the factory it's a surprisingly good snow car so long as one has bona-fide snow tires on it ("all season radials" are not adequate) and don't try to drive through snow deeper than your ground clearance. (I've done it, but it's not fun.)
They look like they would be a lot of fun. Have you put a turbo on yours? A co worker I had a long time ago had one of the first body style. And he did a bunch of work to the suspension on it, and he trailers it to a few states doing races with it every year. When I knew the guy and worked with him he was competitive and claimed to place or win at a lot of the races. But who knows now.
It kinda surprised me to learn but I guess miata racing is really popular. I got maybe 5 payments till my car is paid off. So my wife is going batty wanting a new body style miata or an eclipse. It's funny she currently drives a big *** 7 passenger van (we have four kids) and she is wanting to go to the opposite extreme and get something that's tiny.
