Looking for a car for the track. Want to keep it street legal so I can tool around in it if I want (I will). I'm looking at mostly Porsche 944, Nissan 240sx and 300zx and Mazda Miata. I had a thread up here about 944 that I wanted to buy, but it's rear end gave out a few days after I looked at it

good thing I didn't buy that! Does anyone have any good suggestions for other models and makes? I want to keep the inital cost at below 5,000 (it will be a lot of work and a lot of money will go into it, I know). Start naming!
