Nash was positioning this new product for the emerging postwar market for "personal use" autos. These specific use vehicles were as a second car for women or an economical commuter car. The Metropolitan was also aimed at returning Nash to overseas markets. However, Mason and Nash's management calculated that it would not be viable to build such a car from scratch in the U.S. because the tooling costs would have been prohibitive. The only cost-effective option was to build overseas using existing mechanical components (engine, transmission, rear end, suspension, brakes, electrical), leaving only the tooling cost for body panels and other unique components. With this in mind, Nash Motors negotiated with several European companies. On 5 October 1952, they announced that they had selected the Austin Motor Company (by then part of BMC) and Fisher & Ludlow (which also became part of BMC in September 1953, later operating under the name Pressed Steel Fisher), both English companies based in Birmingham, England and vicinity. Fisher & Ludlow would produce the bodywork, while the mechanicals would be provided as well as the final assembly were to be performed by the Austin Motor Company. This was the first time an American-designed car, to be exclusively marketed in North America, had been entirely built in Europe. It became a captive import – a foreign-built vehicle sold and serviced by Nash (and later by American Motors) through its dealer distribution system. It is believed that the first pre-production prototype was completed by Austin on 2 December 1952. In all, five pre-production prototypes were built by Austin Motors and tested prior to the start of production. The total tooling cost amounted to US$1,018,475.94, (Austin: US$197,849.14; Fisher & Ludlow: US$820,626.80) which was a fraction of the tooling cost for a totally U.S.-built vehicle. The styling for all Nash vehicles at that time was an amalgam of designs from Pinin Farina and his design house of Italy and the in-house Nash design team. The different models from Ambassador down to the Metropolitan utilized similar design features including fully enclosed front wheels, notched "pillow" style door pressing, bar-style grille, etc. The new Metropolitan was made in two body designs: convertible and hardtop. All came with several standard features that were optional on most cars of the era. Among these factory-installed benefits for customers were a map light, electric windshield wipers, cigar lighter, and even a "continental-type" rear-mounted spare tire
