One of Buick’s most famous cars, the Y-Job, regarded by many as the world’s first concept car, has just been added to the National Historic Vehicle Register. It joins other special vehicles from America’s past such as the original Shelby Cobra Daytona Coupe prototype and President Reagan’s Willys Jeep.

A Bugatti fan from Saudi Arabia has just bought two very special models. One of them is the one-off Bugatti Vision Gran Turismo concept unveiled in 2015. It appears the buyer made the company an offer it couldn’t refuse.
