Ever since I put a carpet in my trunk area I wasn't able to use the cargo organizer thing that came with the car. I've been using a couple boxes to hold junk and it's just sliding around. After searching for a while I finally found a pretty organizer that should fit pretty well in the back.I just purchased the Rola 59001 M.O.V.E. Rigid-Base Interior Organizer from amazon.
