The strikingly sleek Chevy Nomad of 1955-1957 brought mid-century modern design to the utilitarian station wagon. The Nomad got its name, along with its unique roofline and rear body treatment, from a 1954 GM Motorama Corvette concept wagon conjured up by GM design chief Harley Earl – father, as well, of the 1953 Corvette roadster.
Encouraged by the show car's reception, and mindful that America's burgeoning suburbs were absorbing ever more station wagons, Chevrolet developed the Nomad into a premium Bel Air-level “halo” model for their 1955-57 regular wagon lines. The Nomad two-door sport wagon design was produced through 1957. Each of the three model years still has its passionate followers – the original Nomads have never gone out of style.
