I Own a Carerra S. Absolutely Love it. After driving a 350Z, all sorts of Evo's and STI's..I still love it..and its my daily driver. Apart from a super loud exhaust, its as practical as my Z used to be. Maybe even more so as it can take more stuff.
On the track its amazing, demands a little bit more restraint when driving as the nose is light, but powering out of corners never felt so great.
That said, I havent driven a Ferrari, but I want one!!!!!!!!
The Porsche is a great sports car...the Ferrari to me is an ICON... It does what its supposed to do...gives you goose bumps, and makes me feel like a kid.
The Ferrari makes me desire a truly impractical object...even seeing a slower 308 on the road makes me want one... to me thats a true exotic!!!! If it can make you do something that doesn't all add up to common sense....
I voted Ferrari... but if i was doing more track days, please get me a GT3RS!!!!!
