Just purchased a used 2004 Aveo. When looking under the front end I noticed a broken piece of plastic hanging down. I pulled the piece off and from the holes in the bumper skin,it appears there should be some kind of air dam or spoiler mounted under there.
You know the part I am looking for, it's always draged over a curb or concrete wheel stop in parking lots. ;) Does anyone have a picture that shows what it is supposed to look like?
