Absolutely, I will share what I find out. So far, I have the four pieces to share with my tax person; Bill of sale, completed form 8936, and the letters (2) from Chrysler (in the link you sent yesterday). The Chrysler letters, one for WA and the other for Federal, should "acknowledge the certification of the vehicle." Fingers crossed!
Still wrapping my head around that $7,500. I heard the same thing - credit is applied to what you owe/burden for the entire year. Not sure about getting anything back if I owe less than $7,500 for 2018. Ugh.
