Yeah, I'm looking under parked cars too. The issue for me is that it needs to look like it belongs on the car. Modding an existing piece should be easy. However, I found some trash cans that can be cut a particular way and look like they belong there (believe it or not). I just need to study and figure out where to place them and how big they should be. My car actually has something on the underbelly that looks like air-dams, but their size and placement is rather odd.
