The Series 1 was introduced, initially for export only, in March 1961. The domestic market launch came four months later in July 1961. The cars at this time used the triple SU carburetted 3.8 litre six-cylinder Jaguar XK6 engine from the XK150S. The 3.8-litre engine was increased to 4.2 litres in October 1964.
The Series 1 can be recognised by glass-covered headlights (up to 1967), small “mouth” opening at the front, signal lights and tail-lights above bumpers and exhaust tips under the number plate in the rear. 4.2-litre cars have more comfortable seats, improved brakes and electrical systems, and an all-synchromesh four-speed gearbox. Optional extras included chrome spoked wheels and a detachable hard top for the OTS.
The Series 1 4.2 offered here has been modified to a fast road example and is fitted with sports triple Webber Carburetors for intake and a tubular stainless steel manifold for the exhaust. It also has an uprated aluminium radiator with thermostatic control, probably as much for beauty as for functionality! This car really is the subject of much recent work which whilst not exhaustive include a full retrim and respray, a new steering rack, hoses, belts, chrome work, door handles, lights, engine mounts, plugs, leads, waterpump, sump, bushes, ball joints, brakes and servo, reaction valve – the list goes on. In fact the vendor estimates that well over £20,000 has been spent in 2017 alone. The car is supported by a Jaguar Heritage Certificate, recent MOT and V5C registration. Believed by many to be the most desirable model, retaining the beauty of the early cars while benefitting from the later modifications, this car represents an excellent opportunity to own one of Jaguar’s best.
