Jaguar XJS 4.0 Coupe

Launched way back in 1975 as a replacement for the E-Type, the Jaguar XJS is one of those rare cars that just got better as it evolved – all too often it is the first model that is the best while the later ones just get lardier and lumpier. The first major facelift came in 1991 when the Big Cat got larger rear windows, new rear wings, different lights and revised instruments. 

It also got the superb new 4-litre 24-valve AJ6 engine, a paragon of refinement and reliability that was virtually as quick as the old V12 but with far superior fuel economy (235bhp, 140mph and 26mpg). Reliability was superb and these AJ6 engines have been known to clock up huge mileages without drama. Build quality also improved markedly with a galvanized body shell finally putting paid to that old Jaguar bugbear – rust.

First registered in October 1993, this particular 4-litre Coupe looks most attractive in Spruce Green Metallic with a grey leather interior. It has covered some 135,000 miles from new but was reputedly fitted with a replacement engine and gearbox from a low mileage armour-plated diplomatic vehicle about 10,000 miles ago. These vehicles have to be destroyed to protect their ballistic secrets when they are taken out of service, but their drivetrains can be re-used.

It is believed that the engine and gearbox fitted to this car had covered some 35,000 miles when installed but the documentation relating to the transplant has been mislaid so this cannot be warranted, although we have spoken to a previous keeper of the vehicle, Brian Reid, technical officer of the XJS section of the Jaguar Enthusiasts’ Club, who has confirmed that this information is correct. Many of the suspension bushes were also replaced at about the same time.

Be that as it may, we have been using this car for the last five weeks and have racked up some 1,500 miles in it and can confirm that it drives outstandingly well with notably good ride, handling and brakes. It comes with all its original handbooks, two sets of keys and is taxed until April and MOTd until July.
