World War II brought to Rüsselsheim the only year in the history of Opel – 1945 – in which it produced fewer vehicles since that first Lutzmann-authored Opel was made in 1899. Before the conflict broke out, the Adam Opel AG had established itself as the largest motor vehicle manufacturer in Europe. The combination of Opel know-how with GM resources had produced outstanding results. In spite of stifling red tape, the economic atmosphere in Germany in the 1930s had powerfully fertilised the growth of this and other auto companies, but in the case of Opel, at least, the expansion of this industrial machine clearly was not directed in any way toward military objectives.

Within Opel the Calibra was a car with potential but sadly much of it was unrealised. Valmet Automotive in Finland, who had a manufacturing facility that build Calibras alongside the German plant, produced two handsome convertible prototypes that never saw production. A Saab coupe based on the Calibra was also rumoured but, again, never saw the light of day.

Typically, although a far better car, like the Chevette all Kadett models have been the butt of jokes in Europe, particularly for being very common (the quintessential middle-class car in Germany and the Netherlands), very prone to rust and very easy to steal. While essentially good cars, and always praised as such by contemporary press, these gave Opel its commoner reputation it is still struggling to shake off.
