1991 Jaguar XJS 5.3L Petrol · L590 DBB

The most recent DVSA examination on 21 April 2022 recorded a PASS with no defects or advisories, and this clean outcome is consistent with the preceding two tests from January 2021 and January 2020, which also passed without recorded defects. The absence of any advisories, monitoring items, or recurring failure patterns across three consecutive examinations suggests that, at the time of testing, the inspector found no components at the marginal stage of wear that would warrant flagging for the owner's attention. While this indicates a stable and well-maintained presentation at the point of each test, it is worth noting that the most recent certificate is now over four years old at the time of writing, meaning the vehicle's current roadworthiness has not been independently verified by DVSA during this intervening period, and any deterioration since 2022 will not be reflected in the official record. With a recorded mileage of 65,040 against a 1991 manufacture date, the vehicle has averaged approximately 1,858 miles per year over its lifetime, which is notably low for a car of this vintage. This figure is substantially below the typical annual mileage for a vehicle of this age and points towards either prolonged periods of standing, very light occasional use, or possibly inconsistent recording of mileage on historic MOT certificates prior to the digital system. Such low annual usage carries specific mechanical implications distinct from those associated with high-mileage examples; the components most at risk are not those related to frictional wear but rather those that degrade through inactivity, oxidation, and the drying out of lubricants and fluids. Given the sparse MOT history covering only the 2020 to 2022 period and the evident low usage pattern, a prospective buyer should place particular emphasis on age-related deterioration rather than wear-related concerns. The tyres should be carefully inspected for sidewall perishing and cracking, as rubber compounds degrade with calendar age irrespective of tread depth, and an unused or underused tyre may exhibit dangerous flex cracking even when the tread appears adequate. The braking system warrants close attention for corroded or pitted brake discs and binding or seized calipers resulting from prolonged standing, both of which may manifest as brake shudder under application or uneven tyre wear across the axle. The 12 volt battery is highly likely to require replacement given the vehicle's age, and the cooling system, fuel system, brake fluid, and automatic transmission fluid should all be regarded as overdue for renewal on a calendar basis; brake fluid is hygroscopic and should be changed regardless of mileage, typically every two to three years. Hydraulic hoses, suspension bushes, and drive belt rubber components should be visually examined for surface cracking, while the exhaust system, being ferrous and decades old, is likely to show significant corrosion even if structurally intact. On a physical inspection and test drive, particular attention should be paid to the operation of the convertible roof mechanism if applicable, the function of all electrical systems including interior trim motors and dashboard instruments, and any signs of fluid leakage from the engine, transmission, and final drive. Listen on the move for any clonks or squeaks from the suspension, which on a low-use Jaguar may indicate perished bushes rather than worn components, and check for any pulling to one side under braking which would suggest a seized caliper. The historical low mileage is not necessarily a guarantee of condition, as vehicles that stand for extended periods often suffer more mechanical harm than those used regularly, but it does mean that many major wear items may still have substantial material remaining provided the vehicle has been correctly stored and started periodically. A pre-purchase inspection by a marque specialist familiar with the XJS is strongly recommended to assess the condition of the V12 or straight six engine, the automatic transmission, and the complex electrical systems that are characteristic of this model.
