1987 Jaguar XJ 3.6L Petrol · E367 FUT

The vehicle remains roadworthy, but the maintenance trend shows a clear decline in rubber component integrity and mechanical play. While it passed the most recent 2026 test at 29,774 miles, the tester identified multiple new advisories that were not present in previous years. The transition from a clean record in 2023 to a list of defects in 2026 indicates that the vehicle is suffering from age-related degradation rather than mileage. The mileage profile is exceptionally low for a 39-year-old Jaguar, averaging approximately 763 miles per year. However, the data reveals erratic usage patterns with a significant gap in activity between May 2024 and July 2025, where the car covered only one mile in fourteen months. The subsequent increase of 3,124 miles between July 2025 and May 2026 suggests a recent increase in use. Such long periods of standing often result in dry rot and seized components, which is now reflected in the latest inspection findings. A buyer must prioritize a physical inspection of all rubber-based bushings and seals. The 2026 record flags perishing sidewalls on all four tyres and worn steering rack rubber mountings, which are classic symptoms of low-mileage storage. The recurring slight play in the rear wheel bearings, noted in both 2025 and 2026, suggests that these components have not been addressed and may soon progress to failure. The reported oil leak noted in the May 2026 test requires a close look to determine if it is a minor gasket seep or a significant leak. Given the vehicle's age, the structural integrity must also be verified for corrosion, as the MOT history does not explicitly detail the state of the chassis. The previous failure in 2024 regarding the rear door mechanism indicates that minor mechanical hardware may be neglected until it reaches a point of failure.
