Among the most remarkable things Petter has ever done is rebuilding his sports car to be the world’s first bio-fueled Ferrari. Furthermore, he proposed to his supermodel-turned-physician wife Gunhild on top of a mountain on New Year’s Eve 2008, and then he spent $5 million on the most expensive Scandinavian wedding of all time. As of March 2013, Petter is ranked as the 6th richest person in Norway.
