well when i got mine my sales guy was on top of it and told me exactly where and when its getting there. knew where the delivery truck was, what stops he made and est time (a day off or so) of arrival. I dont think it's GM but the dealer themselves.
You might want to ask your sales guy. From what i was told by my sales guy - they should know what deliveries are coming and have info on transit. I think the dealers not telling you because they know its not coming in soon and dont want to loose a sale. but thats MHO thats all
