I went through BMW of Bellevue. It was built in mid-Oct and I will hopefully be taking delivery this weekend.
I called around to a number of dealerships in the NW and the best I got for a new-build '10 was 3% off MSRP, comperable to the quotes I got for existing '09s. I figured that's alright since I'm getting exactly what I want when I want it - and it makes a heck of birthday present for me.
