1988 Jaguar XJS 5.3L Petrol · F427 KTN

The vehicle’s most recent MOT test on 5 June 2025 at 47,479 miles confirmed full roadworthiness with no defects recorded. This represents a stable maintenance trend over the past three years, as the two preceding tests—one in August 2022 and another in October 2023—also passed without fail. The absence of advisories or recurring failures suggests the vehicle has not experienced persistent mechanical issues, though the 2023 failure (despite no defects logged) is unusual and warrants scrutiny of whether the test may have missed critical faults. The 2025 test occurred just over a year ago, which is acceptable for a classic vehicle, though buyers should verify whether any pre-test repairs were undertaken privately. The recorded mileage of 47,479 miles over 38 years equates to approximately 1,249 miles annually, a figure unusually low for a vehicle of this age and type. This suggests prolonged periods of inactivity or very light use, which could either preserve mechanical integrity or contribute to stagnant fluids, seized components, or degraded rubber seals. The gap between tests—particularly the 18-month interval between the 2022 and 2023 tests—implies inconsistent MOT scheduling, though the lack of failures in those periods does not necessarily indicate neglect. Buyers should cross-reference this mileage with service records to confirm whether the vehicle was stored or driven sporadically, as prolonged immobility can accelerate corrosion or electrical component failure. Given the vehicle’s age and the sparse MOT history, a thorough inspection should prioritise structural integrity, particularly in the chassis and suspension. The 1988 Jaguar XJS is prone to rust in the sills, wheel arches, and subframe, so buyers must verify there is no significant corrosion compromising load-bearing sections. The suspension—including coil springs, bushes, and dampers—should be checked for excessive wear or leaks, as these components degrade over decades of inactivity. Braking systems, especially the rear calipers and discs, may require attention; the 2023 failure (if any) could hint at binding or uneven wear, though no details were logged. Finally, the electrical system, fuel system, and exhaust emissions should be inspected for leaks or degraded components, as older vehicles often suffer from failing injectors, cracked hoses, or catalytic converter issues.
