1909 was a significant year for Cadillac, both for its acquisition by General Motors and the introduction of the Model 30. From the time of its introduction through 1914, it was the only Cadillac model offered. It was based on the earlier 1907 Model G and in 1910 it became the first Cadillac offered with a closed body – the coachwork was by Fisher. Three body styles were offered: a Roadster, a Tourer and a Demi-Tonneau. The latter had a detachable tonneau and could be converted to a runabout. The Roadster and Demi-Tonneau had a sweeping cowl that presaged “torpedo” styling.
