Following Maserati’s successful transition from the racetrack to the open road, the next logical development was a performance sedan, the Quattroporte. In classic Maserati fashion, the Quattroporte was essentially a four-seat supercar, with superb performance provided by a 4.1-liter four-cam V-8 engine which would go on to power Maserati road cars for more than a decade. With intriguing styling penned by the legendary Pietro Frua, just 759 Quattroportes were built.

The stunning Quattroporte offered here, chassis number AM107 012, is the 18th example completed from the total production run of 759 built between 1963 and 1969, according to information provided by Maserati Classiche. It was completed on August 6, 1964, finished in its original colors of Avorio (ivory) over Brown leather, and was originally delivered to a doctor in Cascina Ronchetto, near Milan. By the early 1990s the Maserati had made its way to the West Coast, where it was registered to Alice R Ganzon in Whittier, California. Eventually it became part of the Riverside International Auto Museum collection and was comprehensively restored while in that ownership. The Riverside Museum, founded by the Magnon family and led by Doug Magnon, owned the largest collection of Maseratis in the United States at the time, ensuring that this intriguing Quattroporte was properly preserved and cared for.

In recent ownership, the car has received a $20,000 engine and transmission service, and the differential and driveshaft were replaced in 2018, including new axles and bearings in the independent rear suspension. The brakes were refreshed with a new master cylinder along with new power brake boosters. Modern electric fuel pumps were added and new fuel lines were run, and a new old stock fuel pressure regulator was installed. The Weber carburetors were rebuilt and tuned along with cam phasing and valve lifter adjustments. The transmission was also fully rebuilt. This extensive mechanical recommissioning was completed by Maserati specialists Steve Maxwell and Chris Minks, who did much of the work rebuilding the suspension.

Beautifully presented, chassis number 012 is unquestionably one of the finest early Quattroportes in existence. This is evidenced as Maserati chose this very car to grace their corporate display stand at the Pebble Beach Concours d'Elegance not once but twice. It represents a remarkable opportunity to own a textbook example of Maserati’s first four-door sports car. The Quattroporte is sure to turn heads wherever it goes – with room for the whole family!To view this car and others currently consigned to this auction, please visit the RM website at rmsothebys.com/en/auctions/mo20.
