Sorry for the late reply, been busy these days. I think Dark metallic purple inserts would look sick on your car, I want that color for my actual whole car. I finally got my car back from the shop yesterday, my baby is finally back home and newly dropped on some Eibachs and tinted windows and HIDs.
You were also talking about a rattle...how does it sound? Does it sound like metal is rattling or something inside your cabin? I am sure it is something minimal, you can always check at your dealership, thats why we have such an awesome warranty. Yea and once you have a car that had many problems such as your cobalt, you do get paranoid a bit with every weird sound you hear, I am like that as well. I am just so happy to get my car back, its not 100% perfect but its good enough, it was a pretty big accident. You should def. get some springs, the car feels 100 times better!
