Sorry to say but this thread ends.
Due to unfixable Stabilitrac problems GM bought back my ZL1. This took 4 months.
While I regret losing the ZL1 I do really like my new '16 SS. It is a different car than the 5th gen. I would characterize it as more modern and sporty as opposed to the muscle car feel of the 5th gen. While I enjoyed all of my 5th gens, I think the sixth gen Camaro is more me. A sports car with a small block Chevy. Like a fist in a velvet glove.
