I think it's a great idea to look at the positives at BMW Centers and Workshops, of which there truly are many.
I've been dealing with DiFeo BMW (now BMW of Tenafly after the BMW enforced name change to geographic location) for a long time because of my high satisfaction with the service and support I've received and continue to receive.
I've been really pleased with everything from purchasing my new 335d
(how many cars I have gotten from Ricki, my CA, in the past 10+ years?) to dealing with my SA, Gem and my former SA, Joe.
