That's it, Craig. I read the memoirs of another of Dean Martin Sr's sons, Ricci (RIP), only because he owned a number of interesting cars, including a DeTomaso Mangusta which his older brother Dino wrecked: https://www.amazon.com/Thats-Amore-Remembers-Dean-Martin/dp/1589791401. If memory serves, that Mangusta has been restored and still exists, with its sunroof intact.
