Seems Harry had his Alfa trucked down to Brescia for the Mille Miglia and he flew down drove the car around the event, flew back after the event and the car was again trucked back home..? Perhaps the trucking company might offer a few hints and tips..? The name of the company is on the side of the truck, 4min 55 in to pick up on the trucking company.
