Rare Boschert B300 Gullwing, a Unique Mercedes-Engineered Marvel

Embrace the Fusion of Mercedes Design with Gullwing Doors

An extraordinary 1989 Boschert B300 “Gullwing,” a rare hybrid of two iconic Mercedes designs, is set to captivate enthusiasts at the upcoming RM Sotheby’s auction on November 25. This exceptional vehicle originated as a W124-generation Mercedes 300CE, underwent a striking transformation by German engineer Hartmut Boschert. The car’s roof structure was modified, the chassis shortened by nearly 10 inches, and gullwing doors installed. The front face received a makeover inspired by the R129-gen Mercedes SL-Class, topped with a unique emblem resembling an inverted Mercedes logo. Inside, the B300 Gullwing boasts R129 front seats and a refurbished purple interior.

Performance Comes Alive

Retaining the original 3.2-liter inline-six engine, Boschert enhanced its power with twin turbochargers, yielding an impressive 283 horsepower. The engine’s prowess is channeled through a five-speed manual gearbox to the rear wheels.

Exclusivity at Its Finest

Originally intended to produce 300 units, only a handful of these rare models were ever crafted, making the B300 Gullwing truly a collector’s dream. Recently, in 2023, the vehicle underwent extensive restoration, including a substantial $17,159 mechanical service, $8,236 paintwork, and a $5,048 leather refurbishment.

Auction Anticipation

RM Sotheby’s anticipates the Boschert B300 Gullwing to fetch up to $320,000 at the upcoming auction. While the market abounds with remarkable vehicles, the allure of a 1980s Mercedes with gullwing doors, powered by a straight-six engine and manual transmission, stands out as a testament to automotive ingenuity and style.


The fusion of classic Mercedes design elements with a unique twist in the form of gullwing doors makes the Boschert B300 Gullwing a rare gem in the automotive world. Its blend of iconic Mercedes styling and bespoke modifications creates a one-of-a-kind driving experience that is bound to captivate enthusiasts and collectors alike.
