WHO WAS THIS ACTOR?

I am wondering which male actor played the lead in a 'made for television' comedy special in the 1960s (approx), entiled "My Greek-American Cousin," or "My Visit to Greece,:" or something with the title of Cadillac in it. It was about an American who goes back to Greece to show is affluence with his Cadillac (which does not fit into the narrow streets of the village. Was it Telly Savalas, or someone else who looked 'Greek?"
