1983 Jaguar XJS 3.6L Petrol · JAG 36L

The vehicle currently holds a valid MOT certificate issued on 06 March 2026, confirming its roadworthiness status is stable following the successful clearance of the previous failure. While the record shows a failure on 12 December 2025, the absence of specific recorded defects suggests the issue was likely administrative or rectified immediately without requiring a formal logged repair. This recent pass indicates the car is currently compliant with legal safety standards, though the lack of historical data beyond these two entries prevents a long-term assessment of recurring mechanical trends. With a recorded mileage of 89,945 miles over 43 years, the car averages approximately 2,092 miles per annum. This low-intensity usage pattern is typical for a classic Jaguar of this vintage, yet it raises the risk of issues associated with prolonged periods of inactivity. Components such as fuel lines, rubber seals, and cooling system hoses often perish or seize when a vehicle sits idle for extended intervals. The low annual mileage suggests the car has been treated as a weekend enthusiast vehicle rather than a daily driver, which generally preserves the drivetrain but necessitates a thorough check for age-related degradation. Prospective buyers must prioritise a rigorous inspection of the structural integrity and underbody condition, as the MOT record does not capture the full extent of potential corrosion common in the XJS chassis. Focus your physical examination on the floor pans, sills, and rear subframe mounting points, where rust can compromise the vehicle's structural stability. Given the age of the vehicle, you should also inspect the braking system for signs of binding calipers or perished hydraulic lines, and verify that the suspension bushes have not hardened or cracked. A comprehensive look at the engine bay for fluid leaks is essential, as gaskets and seals on this V12 or AJ6 engine architecture are prone to weeping after years of infrequent use.
