One of Only Four Handcrafted BMW 3.0 CSi Cabriolets Ever Built

Some collector cars are rare because production numbers were low.

Others are rare because they were transformed by master craftsmen into something entirely unique.

This remarkable BMW 3.0 CSi Cabriolet belongs firmly in the latter category. Believed to be one of only four examples ever built, it combines the timeless elegance of BMW’s legendary E9 coupe with the exclusivity of a bespoke handcrafted convertible conversion.

Originally registered in October 1975, this beautifully preserved example has covered just 47,900 kilometers and represents one of the rarest coachbuilt BMW grand tourers available today.

The Legendary BMW E9

The BMW E9 is widely regarded as one of the company’s most beautiful creations.

Designed by Wilhelm Hofmeister and built by Karmann, the elegant coupe became famous through both its graceful proportions and its motorsport success, particularly in European Touring Car Championship competition.

Powered by BMW’s smooth inline-six engine, the 3.0 CSi perfectly combined performance, refinement and long-distance comfort.

Today, original E9 models remain among the most collectible classic BMWs ever produced.

A Bespoke Coachbuilt Cabriolet

Unlike factory-produced E9 coupes, this extraordinary Cabriolet was created by a specialist coachbuilder near Augsburg, Germany.

Only four examples are believed to have been completed, making it considerably rarer than virtually every production BMW of the era.

The transformation was executed to an exceptionally high standard, creating a fully integrated convertible that appears remarkably factory-like while preserving the elegant proportions of the original coupe.

Every detail reflects the craftsmanship associated with traditional German coachbuilding.

Exceptional Craftsmanship

The level of engineering extends well beyond simply removing the roof.

Notable bespoke features include:

  • Electro-hydraulic power soft top
  • Four electric windows with individual switches
  • Illuminated footwells
  • Individual cigarette lighter and ashtray for each passenger
  • Full leather interior
  • Wood sport steering wheel
  • Wood interior trim

These details demonstrate the extraordinary attention paid to luxury, comfort and usability throughout the conversion.

Beautifully Preserved

According to the seller, the car remains in excellent overall condition.

The bodywork received a professional repaint in 2013 while preserving the originality of the vehicle.

Mechanically, the car underwent a comprehensive overhaul between 2009 and 2010, supported by extensive invoices and documentation.

The original interior has been carefully preserved and remains remarkably authentic.

Classic Grand Touring Comfort

Unlike many classic sports cars of the period, this bespoke BMW offers genuine long-distance touring capability.

Equipment includes:

  • Air Conditioning
  • Power Steering
  • Electric Mirrors
  • Four Electric Windows
  • Leather Upholstery
  • Sport Alloy Wheels
  • Immobilizer
  • Footwell Lighting

The combination of handcrafted luxury and BMW engineering creates an exceptionally refined open-top grand tourer.

One of the Rarest BMW Cabriolets

While BMW itself never produced an official E9 convertible, several specialist coachbuilders created a handful of conversions during the 1970s.

Among these, this Augsburg-built example ranks among the rarest known.

Its documented production of just four cars places it in an entirely different category from conventional classic BMW models.

For collectors seeking unusual coachbuilt automobiles, it represents a fascinating chapter in BMW history.

A Unique Opportunity for Collectors

Rare coachbuilt BMWs continue to attract increasing interest among collectors seeking automobiles beyond standard factory production.

This BMW 3.0 CSi Cabriolet combines:

  • Exceptional rarity
  • Elegant E9 styling
  • Handcrafted German coachbuilding
  • Proven restoration history
  • Outstanding originality
  • Grand touring usability

Finding another example of this remarkable model would be extraordinarily difficult.
