Ok so I plan on buying the new SS, but i need to know sum things first. Please dnt sit there and try to tell me the cobalt is perfect. Im needing to know the strengths an weakness of the cobalt ss, everything from performance to the interior. Any major issue's? I heard that GM offers a performance tune for the cobalt SS that's supposed to put out 20 more HP and 40 more tq, is this true and if so how much? Anything I should know about the car will be greatly appreciated! So far i have chosen the victory red paint job, body kit with high sport wing and of course limited split differential. Thanks!
