Klinsmann, if they indeed have one allocation and promise it to you they can input the order and give you a 6 digit order number as these members have in this post:

The Ordering system is "live" except GM will not pick the allocation up for manufacturer till later on this year or at the very first of next year.
So in reality they can do something provided they have been allocated a order shell and ordering instructions from GM.
