[Doesnt Matter]

First off i dont care if you dont like a cobalt i am just looking for opinions and suggestions on what to upgrade. I am looking for rims, a body kit and anything else you believe would look good on a yellow cobalt lt. I am also looking for performance options as well. Please post your suggestions below with pictures and prices if you can. Thanks
