FWIW, my earliest memories include riding in the Ford my parents owned, when I was 3 years old....
OTOH, my father was a Jewish kids from Brooklyn, who registered Republican, straight out of high school (beating his classmate, Norm Podhoretz by a good several decades).
I never had an idea that there were Jews who wouldn't buy a Ford until I met my future wife in college some 38 years ago. I was driving a Ford on our first date, actually. But I'm sure she'd freak out today, if I came home with a new one. Not that she doesn't understand that it's probably pointless, but old traditions die hard, I think.
