It's really not that bad. I think I'm just going to duct tape it from the inside, until I find someone who's replacing his stock bumper. The bigger problem is that most of the retainers on the underside of the rear right wheel well that hold the bumper are broken.
Been living there for the past 2 years and not a scratch on my crappy 15-year-old sentra. Have had the xB for barely a week, someone cracked the bumper.
