Argonaut 

The Argonaut was an American automobile manufactured from 1959 to 1963, or at least the company is listed as being in existence during those years. The Argonaut Motor Machine Corporation was based in Cleveland, Ohio. 

The company announced its production plans for a line of U.S.-made luxury cars in September 1958, planned as the finest and most luxurious in the world. The prices quoted ranged from a low of $28,600 to a high of $36,000; a variety of stainless and other special steels were proposed for the car's manufacture. A supercharged V-12 ohc aluminum air-cooled engine developing some 1,010 bhp (750 kW) was designed for the Argonaut, and all cars were to carry a four-year guarantee. The company claimed, in its catalogue, that two of its models (the "Smoke" and the "Raceway") had maximum speeds approaching 240 mph.

A number of high tech features were claimed, among them special tires with interwoven strands of steel to withstand sustained speeds of 200 mph, electric shock absorbers (individually adjustable from the cockpit) and 3 independent braking systems.

In a 1987 interview, Luntz said that an influential group of backers "felt that to put Italian bodies on an American chassis would infuriate the steel companies". In one article, these Italian coachbuilders were stated to be Bertone and Touring. Luntz also stated that 3 Argonaut prototypes were built, but all research since has only verified one surviving example: a 392 cubic inch Chrysler marine V-8 engine and 3-speed manual overdrive transmission mounted in a custom-built rolling chassis, but without any body.
