1988 Jaguar XJS 5.3L Petrol · F708 KRO

The most recent MOT test for the 1988 Jaguar XJS, conducted on 2022-05-23, resulted in a passing grade, though it included an advisory regarding the near-side front wheel bearing exhibiting a slight noise. This advisory, classified under category 5.1.3(b)(i) in the DVSA’s MOT test manual, indicates a potential developing issue that may not currently affect roadworthiness but warrants monitoring. Over the preceding decade, the vehicle’s MOT history reflects a stable maintenance trend, with no recorded failures or critical defects beyond this single advisory from 2022. The absence of repeated failures or worsening conditions suggests that while the wheel bearing may require closer attention, the overall mechanical integrity of the vehicle remains consistent with its age and usage profile. This consistency is further supported by the lack of significant defects in earlier MOTs, which all passed without advisories or failures, reinforcing the reliability of the vehicle’s core systems under normal operating conditions. The recorded mileage of 57,873 miles for a vehicle aged approximately 38 years is notably low, translating to roughly 1,523 miles per year. Such a low annual mileage is unusual for a car of this vintage, particularly one that has seen extended periods of storage or limited use. Lower mileage can mask wear on consumables such as brake pads, tyres, and fluids, as these components may not have encountered the same levels of stress as those on higher-mileage examples. However, prolonged inactivity can also lead to specific issues, including the degradation of seals, corrosion from standing fluids, and potential stiffness in suspension components due to lack of movement. The vehicle’s history of minimal annual mileage may also imply that it has not been subjected to the same dynamic stresses as a car driven more frequently, which could theoretically extend its lifespan but may also leave certain systems less tested for wear and tear. Buyers should be aware that this low mileage might not reflect the true operational condition of the vehicle, particularly if it has spent significant time stationary without regular checks or maintenance. Given the advisory on the near-side front wheel bearing and the vehicle’s age and mileage, prospective buyers should conduct a thorough inspection of the wheel bearing and associated suspension components. On a test drive, listen carefully for persistent grinding or humming noises from the front wheel bearing, particularly when cornering or accelerating, as these can indicate bearing wear or seal failure. Check for excessive play or vibration at the wheel, which may suggest a failing bearing or misaligned suspension. Visually inspect the wheel bearing housing for signs of oil leakage or excessive heat, which could point to internal component failure. Additionally, examine the front suspension for signs of worn or cracked suspension bushes, as these can exacerbate bearing noise and contribute to handling issues. If the bearing is confirmed to be faulty, replacement is typically required, with costs ranging from £200 to £400 depending on labour and parts, though this may be offset by the vehicle’s age and potential resale value. For the 1988 Jaguar XJS with its low recorded mileage, buyers should prioritise a comprehensive physical examination beyond the MOT test. Given its age, the tyres should be checked for sidewall cracking or perishing, which can occur even with minimal use due to exposure to environmental elements over decades. Inspect the brake system for signs of corrosion on brake discs or calipers, particularly if the vehicle has been stationary for extended periods, as standing fluid can cause rust and binding. The 12V battery should be tested for health, with a focus on ensuring it holds a charge and has no signs of corrosion or physical damage. Fluid levels—particularly brake fluid, coolant, and engine oil—should be checked for degradation, as fluids can break down over time regardless of mileage. Additionally, verify the service history for any time-based maintenance, such as timing belt replacement or suspension servicing, which may not have been recorded in the MOT history but are critical for long-term reliability. Finally, a thorough inspection of the exhaust system for corrosion or structural integrity is advisable, as standing vehicles can accelerate rust in exhaust components. If the vehicle has been in storage, consider running it briefly to check for any hidden issues, such as engine or transmission leaks, before committing to purchase.
