In 1966, Ferrari introduced a larger version of the Colombo twelve-cylinder engine with a displacement of 4.4 liters and a bore that was four millimeters larger than its predecessor. The displacement of a single cylinder was now approximately 365 cubic centimeters. This value became the basis for the model designations of the vehicles equipped with this engine. As a result of the increase in displacement, the engine power rose to 320 hp. The engine made its debut in 1966 in the 365 California Spyder, a luxury convertible produced in very limited numbers, which featured a distinctive, sensational body designed by Tom Tjaarda. In a second step, Ferrari presented the 365 GT 2+2 in 1967 as a 2+2-seater variant of the model family. This was Ferrari's first four-seater road sports car with rear independent suspension. In view of its size and weight, the 365 GT 2+2 was also referred to in the press as the Queen Mary. The vehicle on offer, with chassis number 13221, was delivered probably to Italy in 1972 and imported to Switzerland in 1973, where it was registered in March of that year. The history of the Queen Mary is unknown until it was purchased by a Ferrari specialist in June 2012. Subsequently, the bodywork and interior were restored by Italian specialists Zanasi and Lupi – unfortunately, there is no documentation of the work, but the vehicle speaks for itself. The mechanics were checked in-house and overhauled where necessary. In the summer of 2025, the Ferrari was taken over by the consignor, who wishes to part with his Grand Tourismo for space reasons. The 365 is in very good condition, the engine runs very nicely, and the gearbox shifts well. The last veteran MOT took place in September 2025.
