Well I've never actually been in a newer gp but I know that I like the body style of the 97-03 gp better. The problem I've always had with these cars are the plastic lookin interior. Looks kinda cheap u know? But I like the newer gp interior better. I wouldn't mind havin a comp g. Its not just the engine its also the paddle shifters and suspension stuff pontiac did to it. Plus they r a little more rare. I dunno if it would be worth it or not. Honestly I love my gtp but if I get rid of it I'm gettin a v8 car. I've grown fond of superchargers after havin this car cause they mod different then n/a cars.
