Cadillac
Cadillac is among the first automobile brands in the world, second in the United States only to fellow GM marque Buick. The firm was founded from the remnants of the Henry Ford Company in 1902. It was named after Antoine de la Mothe Cadillac, who founded Detroit, Michigan. The Cadillac crest is based on his coat of arms.

The group claims to have been given a list of eccentric millionaires in 1972 in San Francisco, identifying Stanley Marsh 3 of Amarillo amongst those who might be able to fund one of their projects and submitted it to him. Marsh's response began "It's going to take me awhile to get used to the idea of the Cadillac Ranch. I'll answer you by April Fool's Day. It's such an irrelevant and silly proposition that I want to give it all my time and attention so I can make a casual judgment of it."
