Ridiculous amounts they ask for the mirror itself ... on my Seat Leon it was R5500 for the whole mirror assembly but "luckily" I'm only missing the cap & mirror (after a slight mishap), cost = R400 for the small plastic cap & R1000 for the even smaller actual mirror glass. FML!
I eventually bought the cap and asked a mirror company to cut me a new mirror but they did such a piss poor job I decided to rather live without a mirror than using their shoddy effort. Still not willing to pay R1000 for the real thing from the stealers.
