The Argonaut was an American automobile manufactured from 1959 to 1963. Originally called the "Argonaut State Limousine," and later the "Argonaut Motor Machine," this vehicle was planned as the finest and most luxurious car in the world. The prototype was mounted on a Chrysler chassis. The prices quoted ranged from a low of $26,800 to a high of $36,000; a variety of stainless and other special steels were proposed for the car's manufacture. A 12-cylinder ohc aluminum air-cooled engine developing some 1010bhp was designed for the Argonaut; all cars were to have carried a four-year guarantee. The company claimed, in its catalogue, that two of its models (namely the "Smoke" and the "Raceway") had maximum speeds approaching 240 mph. One Argonaut is known to have come into private hands.
