Rolls-Royce "The Best Car In The World". The Rolls-Royce motor-car has become an almost universal symbol for perfection. This is not because of any secret formula. The quality of a Rolls is the product of the finest craftsmanship applied to the best materials. Each new model is the outcome of years of experiment and research: each car sold has been passed as faultless in every part. Royce said that they could not sell an imperfect car because the doorman would not permit it to leave. The Dynamometer is a particularly clever home-made device. March 04, 1954.
