Other plants formerly operated by Fisher were reorganized to become the Chevrolet, Pontiac, GM of Canada (CPC) and the Buick, Oldsmobile, Cadillac (BOC) groups.

The Osceola was requested by Cadillac founder Henry M. Leland to determine the feasibility of a car body that was closed to the elements.

By 1913, the Fisher Body Company had the capacity to produce 100,000 cars per year and customers included: Ford, Krit, Chalmers, General Motors, and Studebaker.

One reason for their success was the development of interchangeable wooden body parts that did not require hand-fitting, as was the case in the construction of carriages.

Its capacity was 370,000 bodies per year and its customers included Abbot, Buick, Cadillac, Chalmers, Chandler, Chevrolet, Church-Field, Elmore, EMF, Ford, Herreshoff, Hudson, Krit, Oldsmobile, Oakland, Packard, Pontiac, Regal, and Studebaker.

The building is now part of the Piquette Avenue Industrial Historic District and is being revived by Detroit developers Greg Jackson and Richard Hosey and architecture firm McIntosh Poris Architects as Fisher 21 Lofts, a mixed-use project combining 433 apartments and commercial spaces.

The Fisher company purchased Fleetwood Metal Body in 1925, and in 1926 was integrated entirely as an in-house coachbuilding division of General Motors.

It had more than 40 plants and employed more than 100,000 people, and pioneered many improvements in tooling and automobile design including closed all-weather bodies.

The brothers also mounted a bid to take over Hudson Motors, but their tender offer fell short of its market value and the effort was rejected by stockholders.
