I'm currently using the OEM rubber mats (plain black rubber, not the sport version) and have never been thrilled with the fit...there is always stuff under the mats when I am vacuuming...
We are now moving to Chicago and i just purchased the Weathertech mats today (can't wait to try them on) as they tend to cover more area and create a nice container for anything you might track into the car...
Anyone in SoCal interested in 5 mo. old OEM black rubber mats? Ha!
