Here's the rear end of a Porsche Carrera (996) that's seen some better days, cosmetically. Those protuberances on either side of the license plate may have been black originally, as on my car. The painted versions are available aftermarket (bumperplugs.com, e.g.) and look a lot better, I think. That is, they look a lot better until they get scratched and dinged from parking in Boston. Click for larger and see the damage. Yikes.
