Even though many people were not enthusiastic about it (I never did come to terms with any car with tiny wheels), more than 80,000 were eventually sold in the USA and another 15-20,000 elsewhere. Not long ago, Metropolitans became something of a cult-car here, though that enthusiasm seems to have faded as best I can tell.
The Metropolitan design was conceived by William J. (Bill) Flajole whose concept was accepted by Nash-Kelvinator's creative president George Mason in the form of the NXI show car of 1950. Some NXI styling cues appeared on the redesigned 1952 full-size Nash line, as shown below.
Those small wheels aside, the Metropolitan was cute, distinctive, and American-looking, quite unlike most other very small cars designed in the early 1950s.
