1996 Jaguar XJS 4.0L Petrol · RIA 1

The vehicle is currently roadworthy, but the maintenance trend indicates a pattern of reactive repairs rather than preventative care. The most recent test in August 2025 at 42,248 miles resulted in a pass despite advisories for a damaged mirror and perishing tyres. This followed a significant failure just two weeks prior in late July, where the parking brake and secondary braking systems failed efficiency standards. While the immediate mechanical failures were addressed, the recurring nature of these faults suggests components are only serviced once they fail inspection. The mileage profile is exceptionally low for a thirty-year-old vehicle, averaging approximately 1,408 miles per year. The data shows very little movement between June 2023 and August 2025, with only 72 miles recorded over a two-year period. This stagnant mileage pattern suggests the Jaguar XJS likely spends long periods stationary. In such vehicles, low-frequency use often leads to the degradation of rubber components and fluid systems, which is evidenced by the cracking and perishing tyres noted in the 2025 advisories. A buyer must prioritize a thorough inspection of the braking system, as the parking brake failed twice in both 2024 and 2025. The tester previously found no effort at the secondary brake wheels, which often indicates seized calipers or perished hydraulic lines due to lack of use. Furthermore, the exhaust lambda reading failure in 2024 points toward potential engine management or sensor issues that require close monitoring for fuel efficiency. Given the age and low mileage, a physical check for structural corrosion and the condition of the suspension bushes is essential, as these parts are prone to dry-rot cracking regardless of miles driven.
