The M6 Vert ZL1 is rare. There are only a few hundred in existence (84 made in 2017, approx 150 or so in 2018, probably about the same in 2019). There are a whopping 5 available used nationally on cargurus, a dozen new.
When I bought my car there were 5 available nationally in red hot in July 2017, and a month later only one was left and Chevy didn't make any more until the spring of 2018. I paid ~6% under MSRP before TTT. OTD was right at MSRP.
Don't expect dealers to come down much off MSRP. Buyers have next to zero leverage on these cars. 2019 production is done. So the supply of new cars will get smaller until they make more next spring. So if you want the very last new riverside blue vert in Palmyra, IL, or the hyper blue used 10k miler in NJ, you'll probably need to move quick.

Good luck!
