2012 JAGUAR XJ3.0L Diesel

The 2012 Jaguar XJ presents a stable mechanical trend, culminating in a clean pass on 2 July 2026 at 78,042 miles with zero defects recorded. Prior to this, the vehicle failed its test on 24 June 2025 at 78,022 miles, yet the official record lists no defects for that failure, suggesting a minor issue was rectified before the retest or a procedural anomaly occurred. Since that mid-2025 intervention, the car has maintained a defect-free record, indicating consistent upkeep and resolving any immediate mechanical concerns. The mileage accumulation aligns with light usage, averaging roughly 5,574 miles per year over its fourteen-year lifespan. Between the June 2022 test at 75,466 miles and the June 2024 test at 76,528 miles, the vehicle covered just over 1,000 miles, confirming prolonged periods of stationary use or very short local journeys. The mileage then plateaued, moving only twenty miles between the June 2025 failure and the July 2025 pass, before recording the exact same 78,042 miles on the most recent 2026 test. This stagnation implies the car has barely moved in the last twelve months. Despite the pristine MOT record, the exceptionally low annual mileage and recent stagnation demand a thorough physical inspection. Extended periods of inactivity on a vehicle of this class frequently lead to deteriorated rubber suspension bushes, seized brake calipers, and flat-spotted tyres. A prospective buyer must closely examine the underside for structural corrosion, particularly around the subframes and suspension mounting points, as low-mileage vehicles often suffer from moisture ingress rather than wear and tear. Inspect the condition of the brake discs for surface rust and check the sidewalls of the tyres for perishing, as original or early replacement rubber will have degraded with age regardless of tread depth.
