2010 Jaguar XJ 3.0L Diesel · XJ02 ASK

The vehicle is currently roadworthy, but the maintenance history reveals a persistent trend of structural and mechanical neglect. The most recent test on August 28, 2025 at 106,503 miles shows a pass after an initial failure for a dim rear fog lamp. While the car meets the minimum legal requirements, the recurring presence of an oil leak and subframe corrosion across three consecutive years indicates a vehicle that is managed through reactive repairs rather than preventative resolution of underlying issues. The mileage pattern is consistent with a sixteen-year-old luxury saloon, averaging approximately 6,600 miles per year. Between September 2023 at 102,237 miles and August 2024 at 104,367 miles, the car covered only 2,130 miles, suggesting low annual usage during that period. Such low-frequency operation can often accelerate the degradation of rubber-based components and seals, which are not regularly exercised by heat and pressure, which aligns with the persistent oil leak noted in the records. A buyer must prioritise a physical inspection of the rear subframe. The record shows the component was corroded in 2023 and subsequently painted in 2024 and 2025, which is often a cosmetic measure used to mask structural thinning rather than treating deep rust. You should check for flaking paint or fresh pitting on the frame that indicates the corrosion is returning. Additionally, the oil leak that has remained present since at least 2023 requires a professional diagnostic to determine if it originates from a simple gasket failure or a more significant engine seal failure that could lead to catastrophic oil starvation if ignored.
