I discovered in shopping extended warranties that the "good ones" don't require you go to a specifically BMW dealer and here is the big 'BUT"_ but you must take them to a Certified Mechanic facility. Now, here in California (Land of Fruits, Nuts, and Illegal Aliens), there is such a thing as a "Certified Master Auto Mechanic and my independent, who is certified as such, can obtain all the items a regular BMW repair facility can get.
