2006 Jaguar XJ 2.7L Diesel · 400 BBC

The overall roadworthiness of this 2006 Jaguar XJ presents a stable and improving maintenance trend. The most recent MOT test on 26 November 2024 at 149,642 miles passed without a single defect, mirroring the clean pass recorded on 23 August 2023 at 148,175 miles. A failed test on 10 August 2023 at 148,171 miles appears in the history, yet the record shows no defects documented for that failure, suggesting an administrative issue or an immediate rectification before the pass thirteen days later. This pattern indicates a vehicle currently meeting all required safety and emissions standards. The recorded mileage aligns perfectly with typical usage for a vehicle of this age, averaging roughly 7,482 miles annually over its twenty-year lifespan. However, the recent mileage accumulation tells a different story. Between the August 2023 test at 148,175 miles and the November 2024 test at 149,642 miles, the Jaguar covered just 1,467 miles over fifteen months. This extremely low recent usage suggests the vehicle has spent prolonged periods stationary, which carries its own mechanical implications distinct from high-mileage wear. Despite the clean MOT record, a buyer must inspect the vehicle thoroughly for issues associated with extended stationary periods rather than active wear. The air suspension system requires close scrutiny; compressors often fail after sitting idle, and air springs can crack from lack of use. Tyres will likely exhibit flat-spotting or perished sidewalls given the minimal recent mileage. Brake discs may suffer from surface corrosion caused by standing, leading to binding calipers upon recommissioning. Underbody structural integrity demands inspection for corrosion, as older XJ models can develop rust in subframes and suspension mounting points. A pre-purchase inspection should focus on these dormant-age vulnerabilities rather than consumable wear.
