2003 Jaguar XJ 3.0L Petrol · GL03 GOE

The vehicle presents a currently roadworthy status with an improving maintenance trend following a period of reactive neglect. The most recent test in July 2025 at 25,408 miles resulted in a clean pass, indicating that the mechanical issues identified in previous years have been addressed. This represents a significant shift from the 2022 and 2024 inspections where the car consistently failed to meet minimum standards or returned with multiple advisory-related defects. The mileage profile is exceptionally low for a 23-year-old vehicle, recording only 25,408 miles which averages to approximately 1,100 miles per year. This low usage explains the prevalence of corrosion and pitting on the brake discs, as components that are not used frequently fail to clear surface rust through normal braking friction. Between August 2022 and August 2024, the car covered only 2,411 miles, suggesting it sits for long periods. This pattern of use often leads to the degradation of rubber components rather than mechanical wear. A buyer must specifically inspect the front and rear suspension assemblies, as these have been recurring points of failure. The 2022 failure and 2024 advisories highlighted deteriorated ball joint dust covers, worn suspension arm bushes, and pitted discs. While the 2025 test was clear, the rubber nature of these parts suggests they are prone to drying and cracking due to age. Physical inspection should check for fresh tearing in the rubber boots and ensure that the ball joints have been replaced with high-quality components to prevent future failure of the steering geometry.
