Yea, go in and get a preliminary order #. When i went to order mine, they put all the info on the computer and they printed it out and it had a PO #. They also have the list on a board hanging in the office and there aren't that many on order whatsoever at my dealer. Less than 10 for sure, probably around 5-6.
I went to the dealer today trying to get an event code but he said it hasnt been picked up by GM yet, and that when it does he'll notify me. He said he put me on priority list #1, whatever that means. Didn't know there were different priority lists.
Anyways, you do need that PO # and they have to give it to you. If they don't, that means they havent even ordered it yet.
