2006 Jaguar XK 4.2L Petrol · Y29 MAX

The vehicle is currently roadworthy, but the maintenance trend shows a concerning progression in structural and suspension degradation. The most recent test in April 2026 at 103,131 miles identified corrosion on the rear sub-frame and a worn pin or bush on the offside rear sub-frame. While these faults did not result in a failure, the presence of these issues indicates that the chassis components are beginning to succumb to age and environmental exposure despite the relatively low annual mileage. At 103,131 miles, this 20-year-old Jaguar has averaged approximately 5,157 miles per year. The usage pattern appears consistent over recent years, with roughly 1,000 miles recorded between April 2025 and April 2026. However, low mileage often masks the effects of rubber components sitting stationary, which can dry out and crack over time. The record suggests that while the car is not driven frequently, the mechanical components are suffering from age-related wear rather than high mileage-induced stress. A buyer must conduct a thorough physical inspection of the rear sub-frame to assess the depth of the corrosion flagged in the 2026 test. Recurring reports of worn bushes and pins on the upper suspension arms, dating back to 2023 and 2024, suggest that the suspension geometry is reaching the end of its functional life. The buyer should also verify the nearside front inner road wheel for the distortion noted in 2025, as bent wheels can cause vibrations and uneven tyre wear. The transition from minor consumable failures to structural sub-frame corrosion indicates that the vehicle is entering a phase where more expensive maintenance will be required.
