well... i'm too much of a lurker (have less than 25 posts) so I can't officially vote in the poll yet... BUT...
I do have a cracked front bumper cover... front right lower side.
Tapped a snowbank, and it broke on the lower lip area. Should not have broken, IMO. And, the material is very flimsy / and seems much too brittle, especially in the cold temps of Michigan. If there was an aftermarket option made of a better material, I'd jump on it.
I'm currently waiting for Spring to break here in the midwest before I purchase a new bumper cover and get it painted... all to the tune of around $600 !!
