Mitchell retired from GM in 1977, and left a parting memorial to his love for the long, sleek, nostalgic and racy. He knew it was the (temporary) end of the road for his kind of car: “Realizing that with the energy crisis and other considerations, the glamor car would not be around for long. I wanted to leave a memory at General Motors of the kind of cars I love”.
Here’s Bill with his baby. Don’t know if it was given to him as a parting gift, though.
