As I stated in the previous posts, a major factor in the rise of General Motors during the 1920s was Alfred P. Sloan's establishment of a price-prestige hierarchy for GM's various brands. Over the 50 years from 1941 to 1991, when the Saturn brand appeared, the hierarchy from low to high was Chevrolet, Pontiac, Oldsmobile, Buick and Cadillac. But during the late 1920s so-called "companion" brands were introduced to fill what seemed to be price gaps in GM's line. In 1930 the hierarchy was approximately (there was price overlapping in a number of cases): Chevrolet, Pontiac, Marquette, Oldsmobile, Oakland, Viking, Buick, LaSalle, and Cadillac.
Buick's companion, the Marquette, had far greater sales success than Oldsmobile's Viking dealt with in the second part of this series. That was in spite of the fact that Marquettes were marketed only in the 1930 model year whereas Vikings were offered for both 1929 and 1930. Around 7,200 Vikings were sold compared to nearly 42,000 Marquettes.
Unlike the Pontiac and Viking companion cars dealt with in the first two posts, styling detail differences from the host brand were more distinctive on Marquettes for reasons discussed below.
