Sixt
Martin Sixt started the company in 1912 with just three cars. This was the first car rental company in Bavaria. During World War I, the German Army took the cars. After the war, the company started again, but the German Army took the cars again in World War II. After that war, the company began to grow again, providing taxi services for the U.S. Army in Germany. They also started a taxi business in Munich, which was the first to use radios. In 1951, they created the car rental company called Auto Sixt.
