 Neither of those ventures proved successful enough to assure the profitability of the passenger car business of Gräf & Stift, so the company decided to pull out of it.Its last own model was the rather modern "C 12", fitted with a new twelve-cylinder engine, which was only made in very limited numbers in 1938, when the company ceased automobile production to concentrate on truck and bus manufacturing.Gräf & Stift remained in the truck and bus manufacturing business after 1945, continuing as a family-owned enterprise, being run by members of the Gräf family.
