i have a 04 GTO and i will never get rid of it for nothing. i've had trans ams, camaros, mustangs,and vettes, has more room than any of those cars, rides smoother than a vette, not as fast stock as a vette but u can always mod. very easy to work on did the heads and cam in mine in about 4 hours. the only difference other than the motors between the 04 05 and 06's are the brakes the 05's and 06's brakes are a inch bigger and they have 4 piston calipers instead of two, 04's warp very easy. and for the snow thing i wouldn't know don't drive it in the snow, has traction control, guess thats what its for.
