2003 Jaguar XJR 4.2L Petrol · L40 CAT

The 2003 Jaguar XJR demonstrates a stable maintenance trend, culminating in a clean pass on 2025-05-28 at 159,814 miles with zero defects recorded. This recent outcome mirrors clean passes on 2024-05-16, 2023-05-19, and 2022-05-30, showing four consecutive tests without a single advisory or failure. While this streak reflects a period of straightforward compliance, the complete absence of recorded advisories across four years of testing on a high-performance luxury saloon is unusual and warrants physical verification to ensure minor wear items were not simply overlooked by testers. The odometer reading of 159,814 miles on a vehicle roughly twenty-three years old averages out to approximately 6,948 miles per year, which aligns with typical UK driving patterns for this class of car. The inspection intervals are consistent, occurring annually in May without extended gaps or erratic mileage accumulation between tests. This regular testing cadence shows the vehicle remained in active service year-on-year rather than being laid up for long periods, though the lack of mileage figures provided for individual historic tests limits precise inter-year distance calculations. Prospective buyers must conduct a thorough physical inspection focusing on high-stress mechanical and structural components typical of the XJR platform, despite the clean MOT paperwork. The supercharged V8 engine compartment, complex air suspension system, brake discs and pads, suspension bushes, and structural subframes require careful scrutiny on a ramp to detect hidden corrosion or oil leaks. Consumables and rubber bushes degrade regardless of basic test passes, making a hands-on examination of the underbody and drivetrain essential before purchase.
