Seem like i'm in the week 23 group too. About a month ago (when the car was ordered) i was told that it would go into production week 21, but this seems to have been changed.
Since i live only a 3 hour boatride and about 5 hours driving from Germany, my car is supposed to be delivered in week 26 or 27 at the latest..
I ordered a montego blue 3-door hatchback 118i. Probarbly at about the same price as a 135i for you guys in USA.
