Highlights

First Plymouth rolled off the line on June 11, 1928 and was apparently considered by Chrysler as a 1929 model. Generally Model Q Plymouths are considered 1928 models today and the Model U is considered the 1929.

Advertising claimed “smooth speed up to 60 and more mile an hour.” The Plymouth came from the factory with four wheel internal expanding drum hydraulic brakes and full pressure lubrication.
