Exceptions to the nomenclature of ending names with an "a" include the under-licence built Monterey, the Speedster (also known as the Vauxhall VX220 in Great Britain), GT (which was not sold at all as a Vauxhall, despite the VX Lightning concept), the Signum, Karl, and the Adam. The Adam was initially supposed to be called, "Junior" as was its developmental codename and because the name 'Adam' had no history/importance to the Vauxhall marque.
Overcoming these and other obstacles, Opel finally celebrated the completion of the first postwar Opel Blitz truck on 15 July 1946 in the presence of United States Army General Geoffrey Keyes and other local leaders and press reporters. Priced at 6600RM, the truck was designed to run either on gasoline or on wood gas, for which a gas generator could be supplied. With a ceremonial bouquet of flowers flying from its rear-view mirror, this historic Opel Blitz left the factory gate bound for a buyer in Wiesbaden on 26 July. Further production followed at a rate of 150 a month, and by the end of 1946, the production total was 839. Frigidaire refrigerators were also being made at Rüsselsheim, as were Olympia engines for the NSU Kettenkrad.
It had some crazy mechanical issues. At one point it stumbled and stalled because the carburetor had come loose from the intake manifold and I had to tighten it back down! Another time, my brother was driving it and the brakes failed. Somehow the end of the brake shoe that meets the brake cylinder piston had become worn on one side, causing the piston to slip off the end of the shoe when the brakes were applied, losing braking and squirting fluid all over.
