The Italian Raduno VI 2012 event held by the Alfa Romeo Club of Argentina is an annual gathering of supercar owners and aficionados complete with a Concours d'Elegance. This year's event featured one very special guest in the form of legendary Lamborghini test driver, Valentino Balboni. The event was held this past weekend on Saturday, the 24th of March at the Four Seasons Hotel in Buenos Aires. Valentino Balboni took out this terrific early version of the Lamborghini Countach LP400.
