i'm not a big fan of the opening in the hood, just to see a plastic engine cover. rumors on the interweb are that the engine is underrated, and even if it's not, it's not hard to crank up a few ponies by playing with pullies.
There is a guy around here that has a current generation Z06 - ALL black, including the wheels, and LOWERED. Seeing that sucker coming at you in the rear view mirror gets your attention!
