Mine had Monster Mats in when I bought it but the driver's side wore through very quickly. I looked around for a good fitting replacement, but no luck. I bought a new set of Monster Mats from the dealer after reading somewhere (this forum maybe, or one of the others) that the design had changed. At first I didn't think so because the ribs are still hollow underneath, but on closer inspection, the rib profile has been lowered at the previous wear point, the hollow behind the unribbed section is not as deep and the material feels different (hoping it is tougher). I filled the hollow of the ribs near the previous wear spot with silicone RTV for good measure. It doesn't stick really well, but I cleaned it with lacquer thinner to remove any residual release agent and it looks like it will stay in place. Time will tell I guess.
