2001 Jaguar XJ 4.0L Petrol · 25 AGD

The vehicle holds a current MOT certificate following a pass in June 2025 at 72,443 miles, yet the maintenance history reveals a stagnant condition rather than improvement. Recurring advisories regarding suspension bush deterioration and subframe corrosion have persisted since the 2021 test without resolution. While the tester recorded structural rigidity as not significantly reduced, the continuous presence of severe ball joint dust cover failures indicates deferred upkeep on critical steering and suspension linkages. Recorded mileage sits at 72,443 miles, averaging roughly 2,900 miles annually over the vehicle's twenty-five-year lifespan. Progression between the 2021 and 2025 tests shows minimal distance covered, suggesting extended periods of inactivity. This usage pattern often accelerates the degradation of rubber seals and suspension components due to age rather than friction. The slight increase of 274 miles between April 2024 and June 2025 further confirms limited driving exposure during this period. A physical inspection must prioritise the front suspension arms where dust covers show severe deterioration, as contamination likely compromises the ball joints beneath. Inspectors should probe the front and rear subframes for deep pitting given the repeated corrosion advisories, even if rigidity remains intact. The history of fluctuating service brakes across both axles warrants immediate hydraulic system checks to rule out seized pistons or internal leaks. Finally, verify tyre sidewall integrity against the cracking reported in 2024, as standing vehicles suffer perishing regardless of tread depth.
