General Motors used the GM A platform, shared with the Buick Standard Six and the Oakland Six,[1][2] and the yearly changes were the result of a new business philosophy called planned obsolescence.

The growing popularity of GM's brands, like Oldsmobile, contributed to becoming the largest automobile manufacturer when sales overtook the Ford Motor Company during this time period.

The retail price had dropped considerably from previous years due to the popularity and affordability of the Ford Model T, with the top level sedan at US$1,095 ($19,582 in 2023 dollars [3]).

The Model 30 had a wheelbase of 110 in (2,794 mm) and was offered as a touring car, roadster, closed body sedan, and landaulet.

Coachwork continued to be offered by Fisher Body who was the primary supplier of all GM products at this time, and Duco automotive lacquer paint, introduced by DuPont was the first quick drying multi-color line of nitrocellulose lacquers made especially for the automotive industry.
