I just took delivery of my E90 (my first BMW) on Monday and I wanted to say that I really feel that I got a good deal and great service from VOB BMW. My saleswoman, Nan Wong, was professional, friendly, and knowledgeable -- She answered plenty of questions from a Bimmer newbie, always getting back to me in a timely manner, often by cell phone or Blackberry; while I was anxiously awaiting delivery, she e-mailed me PDFs of the vehicle inquiry reports with each change in the car's status; and on the delivery date, there was a nice walkthrough of the car and no BS!
If you're curious about price, delivery time, etc., see this thread:
