A buddy of mine who owns an '06 GTO gave me a brief ride in his vehicle yesterday morning. I was very, very impressed by how quick it was and how hard it pulled. He's had some work done to it (I think including the throttle body) but its the original cams and heads. After the ride it had me wondering how my stock '11 CTS-V Wagon would do against it! I know in stock form the GTO can't match the V in any performance category, and certainly not the GT-R. But impressive nonetheless!
