You're tellin me that a turbo buick can't be made to handle great in the curves? On the contrary.
On a DEDICATED race track, like you see on that car show Top Gear, the Porsche may have a slight advantage, but on the everyday twists and turns that us normal people face each day on our everyday streets? I could build a GN to just ANNIHILATE a porsche. I'd be willing to put a good amount of money on it too. AND still be one FIFTH the price of the Porsche too. AND be cheaper to maintain.
(Not to mention the 'cool' factor. Porsches around here are a dime a dozen. (birmingham/grosse pointe. Mr. Licht can attest to that) You pull up to a light in a 911, noone cares. Pull up to a light in a Grand National, and people wanna know what's up. Let me tell you that heads are 'a turnin my friend)
