It's not a show stopper either way. The plastic is soft so marks up if people are wearing rings or a careless with keys. Can be plasti dipped, wrapped etc etc. I would say that unless you are a forum member you wouldnt even know this can be an issue. There will be plenty of excellent examples that may have scrathced switch covers. Wouldnt say the person doesnt know the car or is lying. Anyway, moving on....
Good luck sourcing your z
