Chapter 7. The Jaguar XJ40 (1988-1994).
(Version 1 Rough Draft)
1. Overview of various XJ40 models.The Jaguar XJ40 was the result of a 10 year design exercise with the Jaguar design department attempting to best the classic design of the first generation XJ6. The XJ40 prototypes began with a body design very similar to the final result, wandered through the boxy, angular shapes which were popular in the early-1980s, before returning to the body style that we know today as the XJ40.
While the XJ40 body design was simplified greatly over that of the series III XJ6, the XJ40 electrical system became much more complex.
If you interested in the new XJ40 model, then get a copy of the September 1994 Jaguar World magazine. They have an excellent 5 page article on buying a used XJ40. Currently, large numbers of early XJ40's are being dumped on the market at low prices due to many first owner leases ending. The jury is still out on the XJ40, but the picture which appears to be evolving is that, while early models had some some serious problems with their new electrical and mechanical systems, the later XJ40 models appear to be quite robust.
But mine just kept driving along. By comparison, I did 110,000 Kms in the same time and only had a fuel pump, new discs, and repairs necessitated when the thermostat seized and cooked the engine. Other than that one major repair (ouch) for a car of that mileage, I don't think it is too bad." Peter Rebbechi(email@example.com)
2. Specific problem areas with XJ40's.The early 1988 XJ40 models were the least reliable, with electrical problems such as irratic guages, starter and fuel pump failures being very common.
The service record for 1989 models is also poor though the model year witnessed improvements such as new air vent designs that stayed in the dash when moved instead of falling out into your hands, improved switch assemblies for the cluster on both sides of the steering wheel column, and some improvements in the electrical harness.
Metric tires: Early XJ40's came with metric sized tires. The metric tires tend to be more expensive and come in fewer sizes than the more common standard sized tires.
The 1990-93 years were ideal years for reliability. Improvements were made to the power seat motors, improved sealing of the trunk (less leaks) and more improvements in the electrical system. Things to really look for are oil leaks at the right front corner of the head and rear suspension problems. The oil leak tends to be the head gasket and can be quite a problem. Look for oil between the distributor and the head. The rear suspension should be converted to standard to get rid of the hydraulics. After years of testing it has been found not to work properly.
3. Prices of XJ6's:As with any used car, there is no foolproof method for determining what the correct price of a used XJ40 should be. One metric is to see what similar cars are selling for in your local paper. An upper bound for the price can be usually be determined by looking at the prices being asked in the US publication "Hemmings Motor News". Vehicles advertised here tend to be in excellent shape and priced accordingly.
Recently (1995), the prices of XJ40 decreased greatly with the introduction of the new X300 Jaguar sedan. At the same time many XJ40 ownership leases ended and the cars were released to the market place. Lower bound prices for early model XJ40's currently appear to be around US$8000 and headed downward.
