I got my production number locally from Passport BMW, Joern Esser, last week on Wednesday for a 2013 E92. It was the first production # I've heard of for domestic delivery, though I have seen a handful for European Delivery come out before mine.
Joern rules! He's my regular BMW guy. And his dealership is almost as inexpensive as the best discounters we all know and love - only four or five hundred bucks higher.
