I honestly don't know. I got a 2019 at the end of this year right before the 2020's were released. I had found a couple decent deals on Hyundai Konas, which still have the full federal tax credit, and when I pointed this out to the Chevy dealer they came back with a significant amount of dealer cash back.
In the end I got $9k off from the dealer and $2k off from a Maine-exclusive tax credit that is related to VW's emissions fraud settlement.
I think I just got really lucky.
