BMW Karmann Asso Di Quadri, 1976, by Italdesign. Commissioned by the German coachbuilders, Giorgetto Giugiaro’s Ace of Diamonds concept was a pitch to BMW for Karmann to make a coupé based on the E21 3-series. Presented initially at the Turin Motor Show in silver, then later in red, only the concept’s wheels made it into production thanks to Japanese company Melber who licensed the design.
