Strictly BMW prices are very similar to dealer when called them for quotes too. I had to buy new components for a melted lamp socket and strictly BMW parts guy was not as sure about the replacement process as the dealer parts guy who was very helpful. Parts price was the same.

I moved to Seattle from Portland two years ago and still get my car serviced at the dealer in Portland as their prices are the same as aftermarket shops in Seattle. I have heard a few good things about Eastside Bavarian however I never used them.
