I had bad experience with Bekkers, but some people swear they are the best... it really depends on who do you talk to and what do you looking for. My experience is that most BMW parts company has absouletly no or minimal info about the 8 series. Sometimes they have false info. - that is the worst :-( I have never used Zygmund but heard a lot of good info about them and they seems to know what they are doing. I'm about to order from www.germanautoparts.com and they are also very good in response, let's see how good they are in shipping and matching parts
