Good info and thanks! I am just trying to figure out why the mothership and seemingly every dealer (especially mine) is so tight lipped about production status, etc. Transparency would go more than 12 parsecs in goodwill if people knew what, where, when, and why. We do have the 'who.'I originally placed my order during early April 2022. Thereafter, my order had to be redone because the (former) GM inputted it incorrectly (inconsistent with the build sheet provided to me). My revised order was VIN 10xx. That order went "in production" on or about November 3, 2022. Then, during December 2022, the entire model was delayed. I do not know how far along my car was at the time of the December 2022 delay.
Because of the December 2022 delay, I was allowed to change my spec without incurring any additional delays (beyond the overall delay). I placed that new order during December 2022 and, because it was a new spec, I was given a new order number.
The FOK for my new spec/order was originally March 20, 2023. Then, last month, I was advised that my FOK was pushed back to April 21, 2023. The VIN is 15xx.
With the various interruptions along the way, it appears that there is not an absolute correlation between order date and VIN number.
I received a VIN number on or before February 8, 2023 (I have a February 8 e-mail with a VIN number, but I do not know when it was assigned). My car did not go "in production" until five weeks later on or about March 13, 2023. If receipt of the carbon tub is the benchmark for "in production" status -- as stated by a Mod here a few years ago ( 600LT Coupe Builds Completed!!! ) -- than something else must trigger the assignment of a VIN number (or vice versa).
