As the company's most successful early line of vehicles, the Ferrari 250 was produced for over a decade from 1953 to 1964 and resulted in several variants. The Ferrari 250 GT Cabriolet Series II was launched at the Paris Salon of 1959. The Series II was made more practical for grand touring with a more accommodating and luxurious interior and larger boot. The car had the latest Colombo 128F V-12 engine with outside plugs, coil valve-springs and 12-port cylinder heads that produced 240 horsepower. Other performance attributes were improved as well, since the Series II was also equipped with disc brakes, tube-type shock absorbers and a new four-speed gearbox with overdrive. Production started in 1959 and lasted until 1962; during this time, the Series II Cabriolet was the most expensive car in the 250 GT range. In total, 201 Series II Ferrari 250 GT Pininfarina Cabriolets were produced.
