Opel Kadett K-38 Saloon is a German passenger car from the interwar period and World War II. The first Opel Kadett cars appeared in 1936, and serial production continued in 1937-1943. About 56,000 copies of this vehicle were produced in its course. The drive was provided by a single 23 HP engine. The first Opel Kadett cars were presented in December 1936 for the civil market. They were based to a large extent on the Opel Olimpia car, and from the Opel P4 they took over the engine and some suspension elements. At the turn of 1937/1938, the KJ-38 and K-38 Special versions were launched. These were the versions offering higher travel comfort and higher quality of workmanship. At the outbreak of World War II, many of these cars were mobilized and served as staff cars for officers of the German armed forces throughout World War II, from the September campaign in 1939 until the last fighting in Germany in 1945.The Opel Kapitan is a German passenger car that was first presented to the public in 1939 at the Geneva Motor Show. Its serial production was carried out in 1939-1940 and 1948-1970, and in its course as many as eight of its generations. The Opel Kapitan was developed and put into production as the successor to the Super Six model. Compared to its predecessor, it differed significantly in design, which became more streamlined and improved the car's aerodynamics. The suspension and steering were also slightly improved. However, the gearbox and engine were the same in both models. Interestingly, the outbreak of World War II did not stop the serial production of the first generation of the car, which lasted until the fall of 1940 and ended with the production of about 25,000 copies of this car. During World War II, many copies of the Kapitan model were confiscated by the German armed forces and served as staff and service cars on virtually all fronts. After the war, production was resumed in 1948 (2nd generation), and the produced model was very similar to the previous version. A radical change in technical solutions and design came only with the fourth generation of Opel Kapitan, which was produced in the period 1954-1957.Opel Admiral is a German passenger car from the interwar period, World War II and the post-war period. The first copies of this car appeared in 1937, and the serial production of the first generation of this car was carried out in 1937-1939. The car was powered by a single engine with a capacity of up to 3.6 liters and a maximum power of 74 HP. Opel Admiral was developed as a luxury limousine to compete on the civil market with cars of such brands as Horch, Mercedes and Maybach. Its first presentation took place during the Berlin Motor Show in 1937. The car had similar engine power, dimensions and equipment, but it offered all this for a lower price. It was also offered in two body styles: saloon and convertible. However, the outbreak of World War II shattered Opel's business plans for this model. In the course of this armed conflict, many of these cars were mobilized and served as staff cars for officers of the German armed forces throughout the war.
