Oldsmobile Series 20
Car model
The Series 20 was an automobile produced by Oldsmobile division of General Motors in 1909. When the Oldsmobile Company joined General Motors in 1908, the Series 20 was one of the first examples of platform sharing that became GM's most notable business model, as it was derived from the previously established Buick brand from the Buick Model B.[1] The Series 20 effectively replaced the Model F, also known as the Curved-Dash Oldsmobile, when it was discontinued when GM assumed operations, and was replaced by the 1914 Oldsmobile Model 42 "Baby Olds". It was the entry-level vehicle below the Oldsmobile Model A and the luxury sedan Oldsmobile Model Z.[2] It was the first Oldsmobile to use numbers to identify the product, a tradition that would last until the company concluded operations in 2004.[1]
