1977 Jaguar XJ 4.2L Petrol · WGD 672R

The vehicle’s most recent MOT test on 2025-08-22 confirms it remains roadworthy, though the immediate preceding test on 2025-08-19—just three days earlier—was a failure without recorded defects. This anomaly suggests either an administrative oversight or a last-minute correction, as no faults were logged in either instance. The preceding tests in 2024 and 2022 also passed cleanly, indicating no recurring mechanical issues were detected by the tester. However, the lack of advisories or defects across all tests does not preclude hidden wear, particularly in a vehicle of this vintage where corrosion and suspension degradation often develop silently. The recorded mileage of 97,638 miles over nearly 49 years equates to roughly 1,993 miles annually, which is unusually low for a classic car of this age. The gap between the 2022 and 2024 tests—just 19 miles over two years—strongly implies prolonged periods of inactivity or storage. Such low mileage can mask deeper issues, as components may have suffered from moisture retention, rubber degradation, or static corrosion rather than dynamic wear. The absence of mileage progression between tests also raises questions about whether the vehicle was ever driven regularly, which could affect fluid condition, suspension integrity, and drivetrain lubrication. Given the sparse MOT history, a buyer should prioritise an in-person inspection focusing on structural corrosion—particularly around the wheel arches, sills, and subframe—where rust can compromise the vehicle’s load-bearing capacity. The suspension, including coil springs, bushes, and shock absorbers, warrants close examination for dry rot or excessive play, especially if the car has spent extended periods stationary. Brake components, such as calipers and pads, should be checked for binding or uneven wear, as older vehicles often develop sticking mechanisms. Finally, the exhaust system and emissions should be inspected for leaks or excessive corrosion, as these are common failure points in high-mileage classics. The lack of advisories does not guarantee these areas are sound, and a professional pre-purchase inspection is strongly advised.
