01 / THE STORY
History & context
The Alfa Romeo 6C 2500 SS Cabriolet by Boneschi is a remarkable one-off creation that showcases the artistry and innovation of post-war Italian coachbuilding. Built on chassis 915.866, this exquisite cabriolet was crafted by the renowned Milanese coachbuilder Boneschi, a name synonymous with bold and unconventional designs. In 1950, the car was presented at the prestigious Nervi and Venezia concours d’elegance, where it captivated audiences and judges alike, earning top honors at both events. What sets this particular 6C 2500 SS apart is its striking design, which deviates significantly from Alfa Romeo’s traditional styling cues. Most notably, it features a large oval-shaped front grille, a radical departure from the brand’s signature heart-shaped scudetto. This bold design choice gives the car an imposing and avant-garde presence, reinforcing its status as a true coachbuilt masterpiece. The long, flowing lines of the body are further accentuated by luxurious chrome adornments on the hood, adding a touch of opulence to its already distinguished aesthetic. Another defining characteristic of this stunning cabriolet is its use of large white-wall tires, which enhance its grand and elegant stance. The combination of these refined design elements with Alfa Romeo’s legendary engineering results in a vehicle that is as captivating as it is sophisticated. As a one-off creation, the Alfa Romeo 6C 2500 SS Cabriolet by Boneschi remains a rare and highly sought-after piece of automotive history. It embodies a unique moment in time when Italian coachbuilders experimented with daring and artistic expressions of luxury.
