According to MotorTrend in 1952, the then new Aero was the number two American car that year, Cadillac being #1. MT had four or five categories of testing, the Aero was #1 in two of them and near the top in the other three. Cadillac never hit number one, but was consistently near the top. So MotorTrend, based on that input (and probably the fact that GM was a heavier advertiser than Willys-Overland), made Caddy #1 and the Aero #2, beating all the Ford, Chrysler and independent products (Kaiser, Nash, Hudson, Studebaker, Packard and Crosley) and the remaining GM brands.
