The AWD helps with the launch, the advantage ends there.
Which much simpler car in it's price range surpasses it at the circuit?
And the only reason I labled your remarks as domestic fanboyism isn't becuase you like the Z06 better, I like the Z06 better as well, but becuase you pretty much called the GTR over priced and under performing, yet gave the Z06 praise when it has similar price and performance.
Look is all subjective, performance isn't, so that really has nothing to do with it.
