The LaSalle Series 52 was a series of cars that was introduced for the 1940 model year. Also known as the Special Series, the Series 52 was related to the LaSalle Series 50, but featured a lower and wider body. These cars were powered by a 5.3L Cadillac V8 engine, and were available in sedan, coupe, and convertible body styles. A limited production car, the Series 52 was only available in 1940, as it was the last year of LaSalle production.
