[04RedLine04]

I belive its because 04 was the first model that came out and due to the fact of just releasign a new generation of 2.0 supercharged they learned alot from the 04 and fix the 05 and 06 alot better no matter how many times u take it to the shop what ever the factory does is way better than any mechanic will do for your car mostly all recalls ,cam position sensor intercooler wires, fuel feed assembly & a bunch more were already repaired by factory on 05,06 models. I have had a hard time trying to keep up to 06 redline but im there and my way of thinking is that if im stock & I dont beat a stock 06 I am not doing no stage kit pulley or any performance parts cause it think its gay that u have a bunch of shit done and a 06 redline stay half way down your door (not saying any names here lol)

Ps. Isuck at grammer dont hate
