Enzmann 506 classic cars for sale

History of the Enzmann 506

Dr. Enzmann developed the Enzmann 506 in Switzerland, with construction beginning as early as 1953. The prototype received its first public appearance at the IAA in Frankfurt in 1957, where its model number '506' referred directly to the stand number. Across its production period, only 80 to 100 units were built, making it an exceptionally rare offering. Dr. Enzmann and his team used a Volkswagen Beetle (Type 1) as the technical foundation, and the model was predominantly sold in Switzerland and Germany. There were efforts to access the US market, partnering with renowned performance parts supplier OKRASA. Production came to an end because of changing legal requirements and limitations in the structural stability of the negative GRP moulds. The manufacturing process itself, especially the coachwork, upholstery, and paint, was a truly hand-built affair in Switzerland, and the cars are renowned for their detail-focused craftsmanship.

Model History

The Enzmann 506 did not have a clear predecessor or successor in the classic sense; it marked Dr. Enzmann’s unique answer to the mid-century roadster challenge. The chassis was directly based on the VW Beetle, and over the years both original models and a small number of faithful recreations appeared – with nine new builds constructed between 2006 and 2014 by Kari Enzmann, Werner Schreiber, and Walter Gossweiler. Later models benefited from a blend of period and modern components, but remained extremely limited, upholding the car’s reputation for exclusivity.

Highlights and Distinctive Features of the Enzmann 506

The Enzmann 506 stands out for its lightweight GRP body, custom-fitted over classic VW Beetle underpinnings. Attention to engineering saw the use of high-performance Porsche 356 and OKRASA motors, often tuned up to 100 PS with special camshafts and twin Weber carburettors for enhanced performance. The car’s unique look integrates Karmann Ghia or Peugeot 403 lights and a full original Porsche 356 A/Pre-A dashboard, with rare Nardi wood steering wheels typically featuring an Enzmann horn button. Accessories were also dealer-branded. The combination of hand-built finish, genuine period components and impressive engineering make it a focal point for aficionados of rare continental sports cars.

Technical Data

Special Editions and Collectible Models

A particular rarity among rarities, only about 80 to 100 original Enzmann 506s were built, with an additional batch of nine authentic recreations produced between 2006 and 2014. These later builds, handled by Kari Enzmann, Werner Schreiber, and Walter Gossweiler, preserved the spirit and mechanics of the originals, ensuring the model’s continuity among collectors aware of its hand-crafted lineage. Official dealer badges and period-correct accessories also enhance collectability.

Weak Spots and Common Issues

While little detailed information on persistent faults exists, prospective buyers should note the original hand-laid GRP bodies may be sensitive to long-term wear or improper storage, as reflected by the historical end of production due to mould stability. Buyers should verify the condition of the fibreglass, check for authenticity of Porsche and period VW components, and pay attention to the correct functioning of the intricate bespoke details, such as original instruments, switches, and upholstery.

Engine and Performance, Transmission and Handling

The Enzmann 506 delivers surprisingly brisk performance for a car of its vintage, thanks to its low weight and the use of high-quality powerplants. The combination of Porsche 356 engines (up to 100 PS), Beetle chassis, and uprated suspension leads to nimble, responsive handling characteristic of mid-century lightweight European sports cars. Each car may feature optimised elements—such as ventilated disc brakes up front or Porsche 356 drum brakes at the rear. Period Michelin tyres and Lemmerz/KPZ wheels ensure authentic driving dynamics. Given the exclusivity of the 506, every model is highlighted for its hand-built originality, with some having rare motorsport or high-performance specifications, such as the usage of Porsche Fuhrmann or OKRASA engines.

Interior, Comfort, Exterior and Design

The design of the Enzmann 506 is defined by its clean, aerodynamic GRP body, hand-shaped in negative moulds for distinctive lines and period-appropriate details. Noteworthy exterior elements include period-specific headlights, integrated indicators from the Karmann Ghia or Peugeot 403, and authentic Hella taillights. Interiors are fitted with original Porsche 356 dashboards, VDO or Störk gauges, and most cars feature original Enzmann bucket seats—often finished in leather. A large rear lid offers practical boot access and, unusually for a roadster, makes fitting an emergency rear bench seat possible. Sought-after accessories such as Nardi wood steering wheels and official Enzmann dealer badges add further distinction.

Other Relevant Features

Mechanically, the Enzmann 506 uses a blend of period-correct upgrades and original Beetle components—like the front axle, various switches, and heating system, which operates similarly to a Porsche 356. Special exhaust systems, occasionally crafted from stainless steel (V2A), and extra oil cooling were standard on many cars. Some later vehicles also incorporated enhancements for comfort and reliability while preserving historical accuracy.

Summary

The Enzmann 506 is a uniquely Swiss contribution to the classic sports car world, expertly blending German engineering with Alpine craftsmanship. With production numbers just exceeding a handful of dozens, and a specification sheet that reads like a greatest hits of 1950s performance parts, the 506 will appeal to anyone seeking a rare, mechanically fascinating, and thoroughly individual classic sports car experience.
