So that makes the S2000 8.7" shorter in wheelbase, 13.9" in length, .1" in width, 5" lower in height, 1.1" in front track and .5" in rear track. With the exception of length, every measurement is less than one foot. Sounds pretty even to me. So much for "tiny sports car".

I've driven FRS's (which in stock form are way underpowered and don't handle all that well at all without suspension work), STi's, EVO's, Porsche's, Alfa Romeos, Jaguars, and even Corvettes (which I raced for 4 years). There's a fine line between road feedback and total isolation. If you can't (or don't want to) tell the difference between the road surface and the shoulder (or the track edge), you can drive a Buick. Too much dampening of road feel is not ideal. The Si isn't bad, there is some feedback, but not to the degree that I'm used to. Different strokes and all that.
(Incidentally, I'm not getting on your case, it's that my car background is probably a lot different than yours (how many rear-drive cars have you owned or driven? That's all I drove for a LONG time). I look for different things than you do and steering/road feedback is one of those things).
