After the war and right up to the present day, many hundreds of companies, hobbyists and designers around the world have built countless special vehicles based on a Volkswagen chassis. Some were adventurous, others breathtakingly beautiful, including coupes, convertibles, pickups and buggies. After 1945, most cars were developed out of necessity, as the market had been bombed out of existence. Later, car manufacturers let their imaginations run wild. In addition to the official production in Wolfsburg, a separate branch of the industry developed around fitting new or good used chassis with custom bodies. Nordhoff refused to supply car manufacturers with chassis from the assembly line. He even prohibited VW dealers from supplying VW Beetles to coachbuilders. All these efforts could not prevent a diverse range of vehicles based on Volkswagen and Porsche technology from appearing almost everywhere in the world.

While in the 1950s the focus was on reconstruction, in the 1960s and 1970s the vehicle was increasingly at the service of leisure activities. The world was becoming more colourful, and not just because of the hippie movement.

Nearly 900 images of vehicles using key components from Volkswagen or Porsche testify to the ingenuity of professional and private car makers.

Austrian historian Thomas Braun has spent more than ten years researching and compiling everything that has been designed and produced in special vehicles based on the Volkswagen chassis around the world. He has also unearthed modified rear-engined VW buses and numerous sports cars that looked like Porsche models or were powered by Porsche engines.
