Jaguar's long awaited V12 was at the heart of the E-Type Mark III. The XJ6 also shared the same engine making Jaguar, Ferrari and Lamborghini the only three manufacturers offering a V12 road car. The Mark III can be distinguished from its predecessors by a larger, chrome plated radiator grill, flared wheel arches and a power 'bulge' on the bonnet.
With the Mark III, Jaguar discontinued the 2 seater coupe, concentrating on the roadster and 2+2. Unfortunately, the oil crisis took its toll and this, along with customers comparing the Mk III unfavourably with the MK I, led to the end of production of this classic motor car in 1974.
