This 1930 Alfa Romeo 6C 1750 Series IV Gran Sport Spider wears coachwork by Zagato. The early history of this car is unknown; it has been in the United States since the late 1960s in the collection of Keith Hellon. It was later purchased by Jackson Brooks of Colorado. At this point in history, the car was dismantled - a restoration was planned but never completed - with its original engine and 80-percent of the original Zagato coachwork. A short time later, it was sold to Tom Perkins, who traded it back to Brooks a short time later. A professional restoration was done; the engine was uprated to 1861cc to accommodate Brooks' intended use of the 6C in vintage racing. A stone guard was added to the front to provide additional protection.
At the Laguna Seca historic meet in 1985, Alfa Romeo was the featured maruqe. This 1750 was piloted by world champion Phil Hill in race to a very impressive fourth place finish overall. A short time later, it graced the lawn at the Pebble Beach Concours d'Elegance.
In 1986, the car was sold to Art Valdez who participated in the Mille Miglia Storica on three occasions. In the early 1990s, the car was sold to another Californian who showed the car at the 1998 Concorso Italiano.
In 2008, this 6C 1750 Series IV Gran Sport was offered for sale at the Gooding & Company Auction held in Pebble Beach, California. It was estimated to sell for $1,200,000 - $1,400,000. The lot was sold for an impressive $1,265,000, including buyer's premium.
