The Buick Limited was Buick's flagship model line between 1936 and 1942, and, in celebration of GM's Fiftieth Anniversary, a single-year halo car for the Division in model year 1958. Since the 1960s Buick has intermittently used the term "Limited" as a designation denoting its highest level of trim and standard features in its various model ranges.

The Cadillac Series 70 is a full-size V8-powered series of cars that were produced by Cadillac from the 1930s to the 1980s. It replaced the 1935 355E as the company's mainstream car just as the much less expensive Series 60 was introduced. The Series 72 and 67 were similar to the Series 75 but the 72 and 67 were produced on a slightly shorter and longer wheelbase respectively. The Series 72 was only produced in 1940 and the Series 67 was only produced in 1941 and 1942. For much of the postwar era, it was the top-of-the-line Cadillac, and was Cadillac's factory-built limousine offering.
