There was one on craigslist for a while in cleveland, a white NA. You can get em pretty cheap now.. 2-3k. Go for the early years, 90-93. Mazda started adding weight in the later models. 90-93 have the 1.6L and 94+ have the 1.8L. 1.6 revs happier, 1.8L makes more power and torque. I'm not autocross literate really, tried it a few times, have difficulty seeing the cone course lol! I built mine to drift but didn't get a chance because I got laid off and everything slowed down (including the bike build). Next year If you have any questions/concerns about the Miata, PM me
