yeah if you look on autotrader for ss sedans ( cobalts 2009 over $22000 4-door ) you will find a lot of dealers with exzact matches most are shipped to dealers with LSD and sunroof fully loaded but I have also seen traction control which changes the MSRP by 100$ FTW? The normal colors so far Black, Silver, Only seen 1 victory red and 1 summit white so I am guessing all the normal colors will be at a dealership near you . This makes me want summit white even more stupid employee pricing on everything till tomorrow and I can't even get one till october this is an outrage !!! Lots of black not getting that color ...

What a crock
