The first cars were produced in 1899 after Opel's wife Sophie and their two eldest sons entered into a partnership with Friedrich Lutzmann, a locksmith at the court in Dessau in Saxony-Anhalt, who had been working on automobile designs for some time. These cars were not very successful and the partnership was dissolved after two years, following which Opel signed a licensing agreement in 1901 with the French Automobiles Darracq France to manufacture vehicles under the brand name Opel Darracq. These cars consisted of Opel bodies mounted on Darracq chassis, powered by two-cylinder engines.
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.
