Well, I am a little confused by the sudden about face in regards to your choice in cars. For one, the s2000 actually looses to your current car on most performance parameters with the exception of being able to steer via throttle (speed 3 does as well, but it's not the same thing) On the straights the 3 should easily overpower it. So in the end, your going to pay more for a less practical car, just for the "cool" factor. In order to explore the performance envelope that separates the speed 3 and the s2000 will likely happen 1% or less of your time on the road, and even then is dangerous. Choice is up to you, but just be aware your going to be dropping a lot of coin for the sake of change.
S2000 is definitely not a good chick magnet, but then again if your buying a car to draw "chicks" you still have some further life lessons to learn
