2004 Jaguar XJ 3.0L Petrol · NG54 AZZ

The Jaguar XJ presents as roadworthy with a stable maintenance trend. The most recent test on 24 March 2026 at 122,256 miles returned a pass with no defects recorded, continuing an unbroken run of clean results since mid-2023. The upkeep pattern suggests consistent, light use rather than neglect or deferred repairs. Recorded mileage stands at 122,256 against a 2004 build, averaging roughly 5,557 miles per year. The history shows gentle accumulation: 116,082 miles on 31 May 2023, 116,097 by 6 June 2023, 117,599 on 7 June 2024, 119,124 on 28 March 2025, and 122,256 on 24 March 2026. A minor gap appears between the May 2023 failure and the June 2023 pass, but the 15-mile difference indicates the car was corrected and retested immediately. No rapid accumulation or standing periods are evident from the data. The single failure on 31 May 2023 at 116,082 miles listed no defects, pointing to an administrative or non-mechanical rejection rather than a worn component. Across all tests, the tester flagged no advisories on suspension bushes, brake discs, coil springs, exhaust emissions, or structural corrosion. The clean sheet implies prior owners addressed consumables before each examination. A buyer should still commission a physical inspection of age-related items the MOT does not measure in depth. Check suspension arms and bushes for perished rubber, examine subframes and sills for corrosion, and confirm brake calipers are free. Low annual mileage can mask dried seals and flat-spotted tyres from prolonged standing, so assess fluid condition and tyre sidewalls before purchase.
