I love Karl Enemark at BMW Seattle. Tell him Michael with the crazy wagon sent you.
Also, love love David Padgalskas at BMW Portland! Both are very helpful and can work on price.
I ended up going with BMW Seattle on my F31... got them below invoice with a lot of work. BMW Bellevue was so busy, I highly doubt they would be willing to work much on price, let alone even give you a test drive.
