1991 Jaguar XJS 5.3L Petrol · H388 CSN

The 2021 Jaguar XJS presents a clean and reassuring DVSA MOT history, with the most recent test on 22 April 2025 returning a pass and no defects or failures recorded. Across the available examinations in 2022, 2024, and 2025, the vehicle has consistently passed without advisories, suggesting that the fundamental safety-critical systems such as braking, suspension, lighting, and exhaust emissions have remained within prescribed tolerances at each test. The absence of recorded advisories is particularly notable for a vehicle of this age, as it implies either meticulous preparation prior to testing or genuinely sound mechanical condition. While a clean MOT history is encouraging, it represents only a snapshot of roadworthiness on the day of testing and does not guarantee that latent defects, developing wear, or age-related deterioration are not present elsewhere on the vehicle. Overall, the trend suggests stable and conscientious maintenance, though a prospective buyer should still subject the car to a thorough independent inspection given its classic status and the inherent challenges of maintaining a thirty-four-year-old motor car. With a recorded mileage of 67,110 miles against a vehicle age of approximately thirty-five years, the Jaguar XJS has averaged around 1,917 miles annually, which is exceptionally low even for a GT car of its era. This usage profile strongly suggests prolonged periods of standing or only occasional seasonal use, possibly as a collector's vehicle or weekend indulgence rather than a daily driver. Such low annual mileage can be misleading from a condition perspective, as the mechanical wear caused by actual driving distance is often less significant than the degradation brought about by inactivity. Long standing periods can lead to fluid degradation, internal seal drying, corrosion of brake discs and callipers, oxidisation of fuel system components, and deterioration of rubber and polymer items throughout the vehicle. The MOT history reflects tests in 2022, 2024, and 2025, with no intervening annual tests recorded between 2022 and 2024, which may indicate a period of non-use, SORN status, or exemption from testing during that interval. Buyers should be cautious of any inconsistencies between the recorded mileage and the general condition of wear-prone items such as the driver's seat bolster, steering wheel, and pedal rubbers, as these often provide a truer indication of use than the odometer alone. Given the age of this Jaguar XJS and its low mileage profile, a prospective buyer should conduct a particularly thorough physical inspection focusing on the consequences of prolonged standing rather than high wear. The tyres warrant close scrutiny, as tyres older than five years can suffer from sidewall perishing and cracking due to UV exposure and ozone degradation, even if the tread depth remains adequate; check the DOT date code on the sidewall and inspect carefully for any visible crazing or brittleness. The braking system should be examined for seized or binding callipers, which commonly develop on vehicles that stand for extended periods, and the brake discs may exhibit surface corrosion that can usually be cleaned away but should be assessed for any pitting or lipping that might necessitate replacement. The 12-volt battery is highly likely to require replacement or at the very least a load test, as lead-acid batteries typically deteriorate after four to six years regardless of use, and a standing vehicle will almost certainly have suffered deep discharge cycles. All fluid systems should be inspected and serviced on a calendar basis, including the engine oil and filter, coolant, brake fluid, power steering fluid, and automatic transmission fluid if applicable, as these degrade with time irrespective of mileage, and any evidence of weeping seals or perished hoses should be addressed promptly. During a test drive, the buyer should listen carefully for any suspension clunks or knocking noises, particularly over uneven road surfaces, as the ageing bushes, coil springs, and shock absorbers on this vehicle are likely to be original or long-standing components that may have hardened, cracked, or seized. Uneven tyre wear patterns after the test drive can indicate alignment issues or worn suspension geometry. The exhaust system should be checked for blowing joints, corrosion of the silencer and pipework, and any signs of exhaust emissions irregularities, particularly given that the Jaguar XJS V12 engine is known for complexity in maintaining correct fuelling and catalytic function. Cold starting behaviour should be observed, as standing vehicles frequently suffer from fuel system varnish, failing coolant temperature sensors, and degraded ignition components. Finally, verify the provenance and authenticity of the vehicle, including its service history stamps, any documentation of recommissioning work following periods of storage, and confirmation that all VIN numbers match the V5C registration document, as classic Jaguars of this generation are occasionally subject to identity irregularities and modifications.
