2004 Jaguar XJ 3.6L Petrol · OE53 SPU

The vehicle is currently roadworthy, but the maintenance history reveals a persistent trend of structural and suspension wear. While the most recent test in February 2026 at 52,917 miles passed, the failure regarding the offside front upper suspension arm ball joint dust cover indicates that mechanical faults are being addressed only when necessary. The recurring presence of advisories regarding the rear subframe and suspension arm bushes across the last three years suggests that while the car is safe for now, the underlying components are undergoing steady degradation. The mileage profile is exceptionally low for a 22-year-old Jaguar, averaging approximately 2,405 miles per year. Between February 2023 and February 2026, the vehicle covered only 1,152 miles, suggesting long periods of inactivity or very limited seasonal use. This low usage often correlates with the accelerated degradation of rubber components and metal surfaces, as evidenced by the 2023 advisory for perishing front tyres and the consistent pitting on brake discs which typically occurs from moisture and lack of use rather than mileage-related wear. A buyer must prioritize a thorough inspection of the rear subframe to ensure the corrosion noted in 2024 and 2026 does not progress into structural thinning. The tester consistently flagged the corrosion as not seriously weakened, but the recurring nature of this advisory requires monitoring for deep scaling. Additionally, the rear suspension arm bushes and the front ball joint have appeared in multiple tests, indicating they are nearing the end of their. Given the history of pitting on all four brake discs, the buyer should verify the condition of the calipers and lines to ensure consistent stopping performance.
