Yep the SLS is very Awesome..... not that i'm biased.
The answer to the 458 is Alan Simonsen... if you own a Ferrari and want it to win you give him a call.
Car is same spec and similar speeds to the Merc, but it gets around with a lot more drama and noise, where as the Merc doing similar lap times are some what more relaxed / lethargic sounding so its quite deceptive.
I'm still blown away at the crowds reaction to the GT races this year, its all been so positive its amazing to hear / see.
