You found a fine new caretaker

Mark, I want to thank you and your team for selling my plane, I thought the whole process went very well and you found a fine new caretaker for the Harvard. From my end everything was painless except watching the plane fly off. Please thank everyone there for their help and let them know that I appreciate what you all did for me. Thanks again.
