my opinion of both cars.
By figures the S2000 is a faster car. But if you are not an expert driver then you won't be able to cash in on it.
In my case- I am able to handle curves at about 15mph faster on the 330ci only because I know the DSC can protect me if I make a mistake. For the S2000 i am always scared cuz of all the back whipping out, so i take it easy and not try to go crazy. My main reason for getting it was for the drop top and it meets that criteria. If i was a speed freak then I would have gotten the M3, but honestly- I don't think many people are ready for such powerful car. I will wait, learn, attend schools before I get behind one of those. Until then, they are two ends of the spectrum if you compare them. Luxury vs. roadster. Space vs. what space? etc.
