I just had my E91 serviced here:
http://www.avusautosport.com/
It was just an oil change, but I liked the shop and the overall feel. The managers seemed like enthusiast types. When i came to pick the car up, they seem excited to talk about the color scheme I chose, the new Idrive, etc. I plan to use this shop regularly in the future.
