Hey John, welcome to the Camaro side!
I am a recent convert from the European side.
Recent rides of mine include a 2005 Porsche Boxter, 2006 Porsche Carrera, and BMW X5 4.4.
I took delivery of my 1SS RS LS3 about a month ago.
Your S2000 is all about high RPM power. My Porsche's had great torque but nothing like my SS!
Impressions from my first test drive were:
1) this car feels very solid and well put together.
2) this car feels very heavy
3) cornering is surprisingly flat with FE4 suspension
4) this thing stops much better than I expected
5) great engine power everywhere, pulls even harder from 4,000 to redline.
So I bought my Camaro and still was hesitant to really push it through turns cause it felt so heavy, my Porsche's felt like an extension of me. But remember, I was used to driving them on road and on track. The Camaro felt so different!
Two weeks ago I took the Camaro up to the north Georgia mountain roads and discovered the more I hustled it along the "lighter" (more responsive) it felt. I just left it in 3rd gear and ran along from about 2,500 - 4,000 RPM. If I was driving either Porsche I'd be using 2nd and 3rd gear and running the engine between 3,000 to 6,000 RPM. Your S2000 would be running at higher RPM's than my Porsche's, right?
So keeping the tire friction circle in mind and staying tuned in to "the string" connected between the bottom of steering wheel and the gas/brake pedals, I'm very happy with my 2012 SS. I bonded with the car that day.
On my way home from the mountain road trip I came up on a beautiful Ferrari 430, it was spotless and sounded great, too. As I passed it only one thing came to my mind - I'm really glad I got this Camaro, can't think of another car I'd prefer.
