Prototypes, special series & special solutions

We realize individual vehicle upgrades and conversions - precisely, close to series production and documented. Our services meet the highest OEM standards and are ideal for development projects, special solutions and ready-to-drive pre-series models.

Customized solutions for automotive, interior & small series production

Whether it is a one-off production, special equipment or a near-series vehicle - the conversion and construction of vehicles requires experience, care and a deep understanding of processes and materials. We offer you professional support in the implementation of your projects - from the individual prototype to the near-series body. We focus on precise craftsmanship - without our own engineering services, but in close cooperation with your development or design departments.

Our range of services includes

  • Conversions of series vehicles, e.g. for special purposes or individualization
  • Construction of prototypes for pre-series, test series or trade fairs
  • Assembly and integration of specific interior or exterior components
  • Near-series production of small batches with consistent quality


Especially for customers from the automotive industry, vehicle construction, the interior sector or for special vehicles, we offer economical and reliable solutions - on request directly at your site or in our factory.
