Hey everyone, first time posting on this site so hopefully i did this right. Me and a buddy of mine had the idea to spend 3000$ (2000£) this summer on a track day car. The plan is to buy the car then slowly restore,strip, and tune it to our liking. Trick now is to buy the right car. Give you guys an idea of what we're thinking, we were looking at the Mazda Miata NA, E30 325i, E36 325i, and a couple z's 240, 280. Keyword here is RWD, so any other ideas or critiques of our current choices would be great. Ideal car would be something easy to work with, with parts (relatively) readily available.
