2003 Jaguar XJR 4.2L Petrol · WM03 HHT

The most recent MOT test on 10 February 2025 resulted in a pass, although it highlighted deteriorating dust covers on the front lower suspension arm ball joints and a worn rear lower suspension arm bush. When reviewing the history since 2020, there is a clear and worsening trend regarding the degradation of the suspension system and recurring wear on the rear brake linings. While the vehicle continues to pass its inspections, the consistent appearance of suspension-related advisories suggests that the rubber components and joints are reaching the end of their serviceable life. With a recorded mileage of 85,222 miles over 23 years, this Jaguar has been used sparingly, averaging approximately 3,705 miles per year. While this low mileage is generally positive for the internal health of the engine and transmission, it introduces risks associated with vehicle stagnation. Low-usage vehicles are often prone to the perishing of rubber seals and hoses, as well as the accumulation of moisture and corrosion in areas that would normally be kept clear by regular heat cycles and movement. Prospective buyers should pay close attention to the suspension during a test drive, listening for knocks, clunks, or creaks when navigating bumps or turning the steering wheel at low speeds. The recurring issues with ball joint dust covers and suspension arm bushes indicate that a significant investment in chassis refurbishment may be imminent to restore the original handling precision. Additionally, the history of thin rear brake pads suggests these should be inspected immediately for remaining thickness and checked for any uneven wear patterns or brake shudder. Due to the low annual mileage, a physical inspection must include a check for sidewall cracking or perishing on all tyres, as rubber degrades with age regardless of tread depth. It is essential to examine the brake discs for heavy surface corrosion or evidence of binding calipers, which can occur during long periods of standing. The buyer should verify that the service history reflects calendar-based fluid changes rather than mileage-based intervals, as engine oil and coolant degrade over time. Finally, the health of the 12V battery and the integrity of the under-trays should be confirmed to ensure no hidden corrosion or leaks have developed.
