In 1965 Ford tried to sell potential LTD buyers on the fact it was quieter than a Rolls Royce because, as well all know, interior noise is a huge factor in car buying. 15 years later, even though the LTD's low decibel advantage had turned into a barely audible tie, Ford was still proud of that fact the LTD was as good as the Rolls at something.
Long time weekend Jalopnik readers may recall my predecessor's classic ad watch feature of Ford's vintage advertisement in which the new for 1965 LTD out-quieted a Rolls Royce. At several different speeds, the '65 LTD was shown to be several decibels quieter than the significantly more expensive Rolls. 15 years after the original Ford set out to prove the LTD could still beat a Rolls Royce at something besides affordability. When it came time to go testing, Ford engineers quickly found out it couldn't, and this uninspiring commercial was born.
