Input: Consider Input: Question: When did the bicycle company open? Passage:In the popular market, Opel and Volkswagen are most well known. Opel was a bicycle company that started making cars in 1899; General Motors bought it out in 1929, but the Nazi government took control, and GM wrote off its entire investment. In 1948, GM returned and restored the Opel brand. Volkswagen is dominant in the popular market; it purchased Audi in 1964, which eventually led to the formation of today's Volkswagen Group. Volkswagen's most famous car was the small, beetle-shaped economical "people's car", with a rear-mounted, air-cooled engine. It was designed in the 1930s by Ferdinand Porsche upon orders from Adolf Hitler, who was himself a car enthusiast. However, production models only appeared after the war; until then, only rich Germans had automobiles. By 1950, Volkswagen was the largest German automobile producer. Today, the Group is one of the three biggest automotive companies in the world, and the largest in Europe; and is now part-owned by Porsche Automobil Holding SE. , seven different car manufacturers belong to the industrial concern: Volkswagen, Audi AG, Bugatti Automobiles SAS, Automobili Lamborghini S.p.A., Bentley Motors Limited, SEAT, S.A., Škoda Auto, along with commercial vehicle makers Volkswagen Commercial Vehicles, MAN AG and Scania AB. During German reunification West Germany incorporated non-large (near 200 thousands per year) production of Wartburg, Trabant cars and IFA trucks in East Germany.
