From 1972 Jaguar’s 5.3 litre V12 engine was available in the XJ range, and for the Daimler version a name used by the company from 1926 to 1938 was revived. Sir William Lyons had retired from Jaguar in 1972 and the new chairman was FRW (Lofty) England. Lofty England had been a Daimler apprentice from 1927 to 1932 and taken second place in the first ever RAC rally driving a 30/40hp Daimler Double-Six. So Lofty England decreed that the new V12 Daimler would be known as Double-Six.
Unlike the Jaguar, the twelve-cylinder Daimler had the same radiator grill as its six-cylinder sibling, and externally only the badges distinguished them. The Double-Six followed the same changes as the Sovereign from Series I to Series III, although the Sovereign name was transferred to Jaguar, the Double-Six name remained with Daimler throughout Series III production, which continued until 1992.
In late 1972, the particularly well-equipped Double-Six Vanden Plas appeared. On a 4 inches (100 mm) longer wheelbase, this model also received a black vinyl roof to set it apart
A two-door coupé was offered in the Double-Six Series II range from 1975 to 1977, as an addition to the four door saloon. It was marketed as the Daimler Double-Six two door. Soon the style and grace was seen by coachbuilders to be perfect for a convertible version, which Avon Stevens was authorised by Jaguar Cars to build. Along with the cars built at the factory, build kits were also produced but of an unknown quantity.
This spectacular vehicle was built to Avon Stevens specification eight years ago, when it underwent a major body restoration keeping the special order black coachwork. Since that time the car has been in storage but in the last few years has had much other work done including, axels, braking system discs, callipers, suspension, stainless steel exhaust, newly chromed bumpers, wheels tyres and more. The XJ has one of the best rides available renowned throughout the motoring world and this one shows why this 5.3-litre V12 is the car to have on a sunny weekend or continental drive. The car comes with a Heritage Certificate, current MOT and excellent history file.
