The Cadillac Series 355 was a V8-powered luxury car manufactured by Cadillac from 1931 until 1935. It was offered as a 2-door club coupe, 2-door convertible, 4-door convertible, 4-door sedan, 4-door town car, and 4-door limousine. It provided a range of Cadillac below the maker's larger V-12 and V-16 lines. It was succeeded by the Cadillac Series 70/75.

The Cadillac V-12 is an exclusive V-12 powered luxury car that was manufactured by Cadillac from the 1930 through the 1937. Below only the maker's top-of-the-line Cadillac V-16 line, these were powered by the Cadillac V12 engine, furnished with similar custom bodies, and built in relatively small numbers. A total of 10,903 were made in the seven model years that the automobile was built, with the majority having been constructed in its inaugural year. It was Cadillac's first, and is to date, Cadillac's only standard production V-12 automobile.
