I got hit in the rear and a good body shop associated with a dealer fixed it perfectly.
Took a while and involved repainting but also inspection/replacement of several under-bumper supports and even the straightness of the exhaust pipes. Five years later you absolutely can't tell it was done.
I took the opportunity to get bumperplugs to paint my bumperettes to match. Also perfect.
See what a good body shop says.
Also a list of wrecking yards specializing in P-cars is
here. Lots more front end crashes than rears so rears should be available.
