Jaguar Mark X

The Jaguar Mark X, said Mark Ten and renamed the 420G in 1966, was a large luxury saloon built by Jaguar Cars between 1961 and 1970 as the successor to the Mark IX. It broke with its predecessors in styling and technology, with a unitary body shell codenamed Zenith, four-wheel disc brakes and the independent rear suspension with inboard brakes of the E-Type, and it was powered by the E-Type's 3781 cc XK straight-six engine. Its upright nose with four round headlamps became the template for Jaguar saloons for nearly half a century, and the XJ6 of 1968 followed its design. It could reach about 120 mph at less than half the price of a Rolls-Royce Silver Cloud, but never met its sales targets, especially in the United States. Its floorpan lived on in the Daimler DS420 limousine until 1992.
