1988 Jaguar XJS 5.3L Petrol · B29 AMS

Corrosion on all four coil springs and play in the nearside front wheel bearing represent the primary mechanical concerns following the most recent MOT pass on 14 July 2026. While the vehicle maintained a clean record between 2022 and 2025, the 2026 testing cycle introduced several major failures regarding headlamp aim and a side repeater, alongside the current advisories for suspension and wheel bearing components. This shift from defect-free results to multiple advisories suggests a period of emerging wear or age-related degradation in the chassis and running gear that requires immediate attention. The recorded mileage of 42,933 miles over a 38-year lifespan indicates an exceptionally low usage pattern, averaging approximately 1,130 miles per year. Such infrequent use often implies the vehicle has spent significant periods stationary, which can lead to the specific types of degradation noted in the recent records, such as the corrosion found on the coil springs and the minor reflector defects noted in 2020 and 2021. While low mileage generally suggests less wear on the drivetrain and engine internals, it necessitates a closer inspection of rubber components, seals, and suspension elements that can perish or seize due to lack of regular movement. A physical inspection and test drive should focus heavily on the chassis and suspension integrity. The advisory regarding corroded coil springs at all four corners is a significant point of interest; you should inspect the springs for heavy scaling or flaking rust and listen for any metallic clunking or snapping sounds when traversing uneven surfaces or speed bumps. Furthermore, the noted play in the nearside front wheel bearing should be assessed by checking for any rhythmic humming or growling noises that increase with vehicle speed, or a subtle vibration felt through the steering wheel. The lighting failures recorded in July 2026, specifically the headlamp aim issues, suggest that the front suspension geometry or the headlight adjustment mechanisms may require calibration. During a test drive, pay close attention to any steering pull or instability that could indicate the wheel bearing play is progressing or that other suspension bushes are failing. Given the low annual mileage, also verify that the braking system is responsive and free from binding, as long periods of inactivity can lead to caliper seizure or uneven pad wear.
