Prototypes, limited editions & bespoke solutions

We carry out bespoke vehicle bodywork and conversions – with precision, in line with production standards and fully documented. Our services meet the highest OEM standards and are ideal for development projects, bespoke solutions and pre-production models ready for the road.

Bespoke solutions for the automotive sector, interiors and small-batch production

Whether it’s a bespoke build, special equipment or a near-series vehicle – the conversion and bodywork of vehicles requires experience, attention to detail and a deep understanding of processes and materials. We offer professional support in bringing your projects to fruition – from bespoke prototypes to near-series builds. In doing so, we focus on precise craftsmanship – without providing our own engineering services, but working closely with your development or design departments.
 
Our range of services includes:

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


We offer cost-effective and reliable solutions, particularly for customers in the automotive industry, vehicle manufacturing, interior design and the specialist vehicle sector – either directly at your premises or at our factory, as required.
