Perhaps it was Jaguar that invented the sports sedan, at least in its modern definition, when in 1955 the British automaker debuted the replacement for its beloved, highly antiquated Mark IV.

The new car, initially known only by its 2.4-liter and 3.4-liter inline six-cylinder engine sizes, was a breakthrough when it debuted in late 1955. It was the first unibody Jaguar and its complicated suspension had its own separate subframe mounted to the chassis with rubber bushings. The result gave the car excellent ride quality and superior handling, which made it a popular choice with both police and those they were chasing.

When it came time for an update, the Mark 2 that bowed in 1959 was enhanced with a larger greenhouse for improved outward vision. Underneath, its suspension was revised for better road-holding, and four-wheel disc brakes were made standard equipment. The new availability of a 3.8-liter inline six-cylinder engine rated at 220 hp paired with a limited-slip rear differential that made the most of the saloon’s capable chassis.

The Mark 2 3.8 was the rarest of the breed, but it was also the most desirable. The 1962 example presented here comes from the middle of production and is painted a striking white over lush red leather with a burled wood dashboard. A well-optioned model, this Mark 2 includes upgrades such as speed hold—Jaguar’s cruise control—plus air conditioning, a period AM radio, and chrome wire wheels.

This Mark 2 is a reminder that one is spoiled driving a Jaguar; its owner recently completed an extensive drive in Italy. Mechanically, the car is described as impeccable thanks to regular maintenance from its current owner’s private mechanic, with a stainless-steel exhaust system, power steering, and four-wheel disc brakes improving its long-distance credentials. In 2015 it effortlessly completed a ladies-only driving tour of the Tuscany region in Italy.
