I couldn't agree more after reading the quote from Eric on July 6, 2011 (4 reviews down) who said, "If you do your own routine maintenance, know anything about your car, or are under that age of 50, EAS is not the shop for you."
Am not a fan of leaving negative reviews, but it was reassuring to hear that I am not the only one with similar experiences. Was treated/spoken to the same way and was also caught off guard once by them fixing things that had not been discussed, resulting in a much higher bill (this was later fixed).
My experience at EAS was not a one-time deal, and while they were efficient and knowledgeable (and some personal friends of mine still use them), I would strongly recommend you take the extra time and research independent BMW shops around Tulsa. Ask around, see who people recommend, and why. It will be well worth your time.
Wish I had read a review like this when I first went to EAS, as I thought they were the only option other than the dealership. Hope this saves at least one person from the same mistake. Good luck!
