Here is what the client's wife (the actual car owner and only one present in the courtroom when I testified) wrote to me afterward. It has been redacted.
"Dear Frank, I am remiss in thanking you for your expert testimony in my auto diminished value case. Thank you! You did an amazing job just as (Husband) had predicted. You are grace under pressure and you came across as knowledgeable and trustworthy, and I love that (Insurance Company's) attorney couldn’t rattle you one bit. I truly appreciate your time and expertise, and it was so nice to meet you. If you find yourself in this neck of the woods I’d love to take you out for good sushi! Have a wonderful week, Fondly, (Car owner)"
