Dr. Opel Presides as the 10,000th Opel Rolls off the Line (1931)
Opel was the first German car manufacturer to shift from workshop to assembly line production. The first car manufactured was the two seat, green and black 4/12 PS, known as the “Laubfrosch” [Tree Frog]. The car remained in production, with variations and improvements, until 1931.
