I currently own a 05' SRT4 Stage 1, everything else is fully tuned 288 whp/342 ft lbs, and I can honestly tell you I have raced a couple of guys with the supercharged SS and have pulled on them very hard. I am currently deployed, but when I do redeploy, the SRT 4 is sold and I am buying an 07' Cobalt SS supercharged. I love the look, style, and aggressive stance of the Cobalt SS. They are gorgeous cars hands down ,sick of driving a Neon on steroids. Plus my son wants to help me build it, and he loves the look of Cobalts. It will be his car in 8 years.!!!
