Mine had the sport bumper trim and it is purely asthetic as stated. I think it looks nice but is useless imo. While in a parking lot someone had backed into it and cracked the black part that bolts the bumper. I thought it wasn't that bad but toyota doesn't sell just the black part of it. It's all one piece and I think it cost either 499 or 599:jaw drop: I plastic welded it back together and you can only tell if your really close or know what to look for.
Oh well, I guess I will just convince the wife that we need to get an actual bull bar. Or, better yet an off-road bumper and winch! I vote for the latter personally, but we'll have to wait and see what the boss says.
It may look good, but they are made like garbage. I had one on my 2003 Sport and it cracked mysteriously. I put it on my 2005 Limited and a moderate snow pile was too much for it. I have a crack going through it as a battle wound!
