Unlike the glitzier Swiss mountain resorts of St Moritz and Gstaad, the village of Adelboden, west of the Bernese Oberland, is rarely troubled by the peace-shattering roar of Ferraris and Lamborghinis.

No, Adelboden is the sort of Alpine retreat where groceries come from the Co-op, shops sell walking boots and alpenstocks rather than Cartier and Brunello Cucinelli — and the most popular thing to get drunk on is the spectacular view of the surrounding snow-capped peaks.

Few would think of looking inside Adelboden’s former fire station in search of 17 of the world’s most coveted supercars, with a combined value of $50 million.

But that’s what was hidden behind the building’s large steel doors last month as preparations were being made for the first global gathering of owners of cars restored by the California-based Singer Vehicle Design.

Singer focuses on “964” series Porsche 911s built between 1989 and 1994
