Built during one of the most celebrated chapters in Alfa Romeo's sporting history, the car passed through Italian and then American ownership, winning its class at the 1990 Pebble Beach Concours d'Elegance and participating in the Monterey Historic Automobile Races on more than half a dozen occasions.
