I’m in a similar situation. Truck came in two weeks ago. Gm reps had to come and swap out an AC module. Apparently was leaking. Pushed back my pick up date by two weeks. Dealer has been a sweetheart. Let me take pics with the family and car etc. GM is managing the final delivery to owners process like a hawk. Conference calls, etc. the car will have about 200 miles on it when delivered to make sure the issues have been worked out. Apparently I am number 66. So yes, you can get the number if you ask.
