Lorinser - The story of world success. Zero Hour. On March 1, 1930, the automobile master Erwin Lorinser founded in Waiblingen a free vehicle repair shop. Her excellent reputation spread quickly. With his enthusiasm and willingness to take risks, he immediately drew the attention of the former Daimler-Benz AG.

As an official "reseller for passenger cars and commercial vehicles", he took over workshop care and service responsibility. In 1974, Erwin Lorinser handed over the continuously growing company to his son Manfred and appointed him Managing Director. In the branch office Winnenden, which was newly built in 1976, in addition to the sale of passenger cars and commercial vehicles, the sports service Lorinser - today the world-renowned and globally active refining company - established itself.

The sports service Lorinser looks back on more than 30 years of experience in refining Mercedes Benz cars. The sports service has its origin in the engine manufactory. This branch of business developed rapidly and in the mid-70s, vehicles were customized with optical components whose design was already trend-setting at the time. In 1981, Sportservice Lorinser was registered as an independent company in the commercial register.

Now known worldwide as a brand, Sportservice Lorinser today has authorized dealers in 42 countries around the world. The Lorinser brand stands for the individuality and enthusiasm of the automobile, for innovation and design, for technological excellence and the highest customer satisfaction.

Sports Service Lorinser's reputation has quickly attracted a number of celebrity sports and show business clients - including Bernie Ecclestone, Niki Lauda, ​​Alain Prost, Paul Tracy, Shaquille O'Neal, Denzel Washington, Sharon Stone, Arnold Schwarzenegger - to name but a few , Since 2006, Marcus Lorinser has been at the helm of the company and continues to lead the fortunes of the Lorinser Group in the third generation.
