That plastic hang-down bit on the xB's rear bumper pops right off!!
You take out a couple of nylon fasteners, and the whole thing pops off the car. I know because I ran over a deer. The only damage to the car (besides hair and blood everywhere) was the rear bumper. Two support tabs broke off and the lower portion of the bumper popped off clean. It was pretty easy to put it back on - the support tabs just hang there, but the bumper is pretty secure anyway. A really great design by Toyota. I was very impressed.
I have a picture or two around somewhere, but the portion that comes off is separated from the upper bumper by a clean, straight seam.
It would be trivial to take off the lower portion and fair it out with plastic.
DO IT!
