And I think all of the other cars listed are better in some way, Ive tracked everything else (other than an FD) mentioned here - main reasons that they are lighter and faster which is kinda the point of a track car for me.
I would love to take my MR2, 306 and Zed on track on the same day - I already know the other two are more fun and it wouldnt suprise me to find they are quicker too.
Im perhaps a little biased, but you can easily find a decent condition track specced 350hp 200SX for £4K now, you dont have to do anything else and theres loads of room for wheels as well. Zeds are great and all, but they are GT cars, not track weapons IMO.
+1
Having done a few trackdays myself bang for buck I had more fun in my Prelude which was light as anything after I'd removed all the modcons (aircon, abs, PS, sound proofing, balance shafts, interior)
If the post had been "I want a great car for the road and to hoon on the occasional track day" then yes, the Z is almost untouchable, however for a track car and having had one the S2000 would be my number 1 choice for the price - beautiful engine, gearbox, poise and response
