Nice looking car! I had an 04' for about a year, it's been my favorite vehicle and I often regret trading it in. The interior is top notch and the power, man I miss the power. As for the appearance argument. The original GTO was just a run of the mill tempest with some trim and a big ass engine, it wasnt anything flashy or amazing. I loved my Goat because it often went un-noticed until you get on the gas, then people notice.
Enjoy it, the LS1/2 really starts to come alive after you get a few thousand miles on it.
