LaSalle was a brand of automobiles introduced in 1927. LaSalle was created by General Motors in order to give the Cadillac brand a lower-priced, more accessible companion. Although LaSalle sat beneath Cadillac, their cars were built using many Cadillac components, and featured an air of quality similar to its bigger brother. As was common at the time for companion brands, LaSalle offered only one self-titled model which was built in various evolutions, known as Series'. The LaSalle was built in six series: Series 303 (1927-1928), Series 328 (1929), Series 340 (1930), Series 345 (1931-1933), Series 50 (1934-1940), and Series 52 (1940). These Series' were named after the displacement in cubic inches of the engine used except for the Series 52 (The Series 50 was briefly known as the Series 350 before being renamed). After thirteen years of production, General Motors decided to discontinue the LaSalle brand after 1940.
