2003 JAGUAR XJ4.2L Petrol

The 2003 Jaguar XJ presents as roadworthy with a stable maintenance trend. The most recent test on 14 March 2025 at 139,024 miles passed with no defects recorded, continuing an unbroken run of clean passes from March 2022 onward. The vehicle shows no worsening faults, advisories, or recurring mechanical issues across the supplied record. Annual mileage sits at a modest average of roughly 6,045 miles per year for a 23-year-old saloon, indicating light use. The records show gentle accumulation: 132,729 miles in March 2022 rising to 139,024 by March 2025, a total of just over 6,000 miles in three years. A single failed test on 3 March 2022 at 132,726 miles was followed by a pass the same day at 132,729 miles with no defects listed, suggesting a clerical or retest anomaly rather than a genuine mechanical defect. The history is sparse and clean, with no advisories on tyres, brakes, suspension, or corrosion. Given the absence of flagged faults, a buyer should still commission an independent inspection of age-sensitive components not always caught in a pass. The tester recorded no advisories on coil springs, suspension bushes, brake discs, or structural integrity, but a 23-year-old Jaguar XJ is prone to subframe corrosion and deteriorating rubber mounts that a clean MOT does not preclude. Verify the bodywork and chassis for rust, check the rear brake calipers for binding after standing periods, and confirm the timing chain and gearbox behaviour on a road test. The low annual mileage implies the car may have sat unused for stretches, raising the risk of seized linkages and perished seals despite the spotless test history.
