I'm feeling I want a fast rwd roadster as my next car, the only ones that I've thought of are z3m and a s2000. Looked at mx5 but cant see me enjoying their power! Porches is a no go as imagine there parts prices are too steep.
Z3 girly girls car, saved only by the straight 6.
MX-5, good car a bit slow. Default roadster option.
So out of that list i'd have the S2000.
But again at s2000 with only 168lb torque :/ My current clio as 140 odd I think and thatll be much lighter!
You've made the mistake of looking at only engine output, and even worse peak figures. The S2000 is fairly short geared, and makes it's peak torque after the Clio (and indeed all the cars listed above) has run out of revs.
The upshot being, the S2000 feels quick (not rocket ship quick, but enough to have good fun) and pretty nice to drive (EDIT: apart from in the wet

). Just be above 6000rpm when you need to move, and be prepared to change gear a lot.
