Me too, on remembering the commercial. In about '71 or '72 I bought a '65 LTD. It was a quiet smooth car. Obviously never got to compare it with a Rolls but an uncle always had new or near new Cadillacs and after the first ride in the LTD my dad said "this car is sure quieter than Truman's Cadillac"! The LTD had probably 80-100,000 miles on it; many more than the Caddy, anyway.
