We had a “Rags to Riches” guy in our town, wonderful man. He always owned a fully loaded Olds. My brother asked him one day why he did not just get a Cadillac. His reply was along the lines of, he wanted the luxury, but not the snobbery, of being a Caddie owner.
No it wasn’t. Buick was in between Olds and Cadillac going up the ladder. Pontiac and Chevy below. Plus a myriad of other differences starting with the engine. I was there..could definitely tell them apart. I’m talking only about the 50’s.
