Somehow - I suspect it was a drunk cyclist - I now have a hairline crack in my driver side mirror shell. It's not a huge deal but it's annoying all the same. I have seen the chrome after market shells for sale on Ebay and elsewhere. Any observations/experiences out there I need to watch for? Are the ones offered for Golf/Jetta/Passat really interchangeable? I really do not want to by a dealer replacement, have it painted and all that ($$$$). I think the chrome ones look pretty cool.
