Commonwealth (automobile company)

[1] The slogan of the company was "The Car with a foundation", which was in reference to the build quality, including such parts as the frames lined with thick felt to prevent squeaks, chrome nickel alloy steel, and five-inch channel sections.

In November, Markin hired Leland Goodspeed, who joined Commonwealth as the new Vice President of Engineering with the intent of developing a new line of cars.

Hired on with Commonwealth, the plan was to design and produced a new high end closed-body car to be called "Goodspeed".

Leland Goodspeed was known within the automobile race community having broken two Indianapolis 500 speed records: one in 1919 and one in 1921, both driving Roamers, so his brand name was very strong.

Checker Motors continued producing components for GM and Chrysler until the 2009 failures of both companies.
