01 / THE STORY
History & context
The Fiat Decathlon prototype, crafted in 1965, is a unique and charming vehicle that represents a blend of classic Italian design and playful innovation. Built on the chassis of the iconic Fiat 500 D, the Decathlon features a sleek fiberglass body created by the renowned Carrozzeria Sibona Bassano. The design drew inspiration from the popular Spiaggina models of the past, beach-ready cars that embodied the carefree spirit of summer driving in Italy. Once owned by the prestigious Agnelli family, the Fiat Decathlon was a beloved part of their collection, used during sun-soaked summers at their retreat in Villar Perosa. It eventually faded into obscurity, only to be rediscovered in the 1980s, hidden away in a forgotten barn. This rediscovery sparked a meticulous restoration effort, bringing the Decathlon back to life and preserving its unique history and design. After its restoration, the Fiat Decathlon was repurposed as a stylish summer shuttle for guests of a Pietra Ligure hotel, offering a nostalgic touch to leisurely coastal getaways. Today, it continues to charm with its blend of vintage elegance and modern usability, serving as a delightful companion for drives to Osiglia and beyond. The car’s story, from its origins with one of Italy’s most influential families to its current role in leisurely excursions, highlights its timeless appeal and enduring place in automotive history. With its fiberglass body, crafted by Sibona Bassano’s artisans, and its historical significance as part of the Agnelli legacy, the Fiat Decathlon embodies a rare fusion of style, craftsmanship, and heritage. Whether used as a functional shuttle or admired as a piece of automotive art, it stands as a testament to Italy’s rich tradition of innovation and elegance in car design.
