The Cadillac Series 70 (models 70 and 75) 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. Production of the short wheelbase Series 70 ceased in 1938, but reappeared briefly as the relatively expensive Series 70 Eldorado Brougham 4-door hardtop from 1957 to 1958, while the long wheelbase Series 75 made a final appearance in the 1987 model year.
