2005 Jaguar XJ 3.0L Petrol · YB05 TCJ

The Jaguar XJ’s MOT history presents a stable roadworthiness record, with the most recent test in October 2025 at 108,902 miles passing without defects—a consistent pattern confirmed by the three preceding annual passes in 2024 and 2023. The sole failure in September 2023, at just 103,461 miles, is an anomaly with no recorded defects, suggesting either a clerical error or an oversight by the tester. There is no evidence of recurring advisories or worsening mechanical issues, which would typically indicate neglect or progressive wear. The absence of defects in the past two years implies that, at the very least, the vehicle has been maintained to meet minimum legal standards, though this does not preclude hidden wear or deferred repairs. The mileage accumulation of roughly 5,186 miles per year is unusually low for a 21-year-old vehicle, particularly one of this model’s vintage. Between October 2022 and October 2025, the odometer advanced by just 7,757 miles, suggesting either infrequent use, long periods of inactivity, or potential odometer tampering. The near-identical mileage on the failed and passed tests in September 2023 (103,461 vs. 103,470) further raises questions about whether the vehicle was genuinely driven or simply moved for the test. Such low mileage reduces expected wear on consumables like tyres and brakes, but it also means components such as suspension bushes, coil springs, and hydraulic systems may have stiffened or degraded from prolonged disuse. For a buyer, the lack of MOT defects is reassuring, but the vehicle’s age and low mileage demand a thorough inspection of components prone to deterioration when unused. Pay particular attention to the suspension—check for hardened or cracked bushes, degraded coil springs, and any signs of binding in the steering or dampers. The braking system should be scrutinised for seized calipers, glazed discs, or uneven pad wear, as stagnant fluid can accelerate corrosion. Exhaust emissions may also warrant testing, given the potential for carbon buildup in a rarely driven engine. Structural integrity is another critical area; inspect for corrosion in wheel arches, sills, and underbody panels, especially in a Jaguar where rust can compromise safety-critical components. The absence of MOT advisories does not guarantee these areas are sound, so a pre-purchase inspection by a specialist is strongly advised.
