Well I've been reading this thread for quite a while now and looks interesting. I recently moved over from a Pre-Ordered 2010 Camaro 2SS to an 09 GT500 and I'm very satisifed with my decision. Even though it's stock, the car is fast. Very fast. One thing that really made me decide on going with the GT500 was the price. For a couple of thousand dollars more, I was able to get more power, better interior and a whole lotta room for upgrades. And from what i've researched on the mods, it's less expensive than i thought. For about 1100 bucks, i can bounce the HP numbers close to 570-600RWHP on stock blower. I can't imagine what a KB or Whipple will do on it. BTW, the 2010 GT500 has somehow taken away the blower whine on the gt500.
That's part of the excitement on these cars. That's another reason i stuck with an 09. Also im not to happy with the rear look on it although the wheels look very nice i must say..
