When you place an order with a dealer, the status is 1100, PREIMINARY ORDER ACCEPTED. UNTIL GMAD ACCEPTS the order, it just sits there at 1100. You don't have an order with GM at this point, you only have a dealer requesting an allocation for a slot in the production schedule. Dealers are awarded allocation based on past performance. Your dealer MUST get GM to accept the order and salesman are known to string along customers during this process. When GM accepts the order, (see 2000 below) all the parts are available and will be allocated to your build.
