Had my SRE in place since Nov. 2020. Double checked with the dealer that it was an SRE order and not a TRE over a month ago and it was good to go (an SRE) and am at #1 at my dealer.
I was also told than if it passed that the 2022 Z06 was ready to be ordered, I could switch to a Z06 and maintain my place at the head of the line.
