The mid-Fifties was before Chevrolet offered a range of subcompact, compact, mid-size, and full-size cars. If you walked into a Chevy dealership in 1957, there were two basic cars: The 2-seat Corvette sports car, and the full-size Chevrolet.
The latter, however, was available in a bewildering variety of configurations. There were three basic trim levels: the 150, the 210, and the top-of-the-line Bel Air. Further, each of the three trim levels could be had in a number of coupe, sedan, and wagon configurations. (See this '55 Sedan Delivery as an example.)
In the photo above is a 1957 Bel Air sedan in Tropical Turquoise and India Ivory, classically hot-rodded on mag wheels and fat raised white letter tires.
