The Jaguar XKE has to be one of them. Probably won’t be listed as there were so many made.
When I was growing up in the early 60s there was an old man, a rich old man, who drove one of those Mercedes sports cars around town.
I doubt if he ever got it over 50. He typically cruised around at maybe 30mph.
