1996 Jaguar XJS 4.0L Petrol · 3 BBS

The vehicle presents a generally stable mechanical trajectory, culminating in a clean pass on 9th September 2025 at 112,671 miles. The maintenance trend appears to be improving, as the tester recorded zero defects in the most recent test. The preceding failure on 8th September 2025 at 112,670 miles highlighted minor administrative oversights—a non-functional horn and an ineffective bonnet primary retaining device—rather than serious mechanical deterioration. These were promptly rectified within a day. Earlier, in August 2024, the tester flagged a cluster of issues including corroded brake pipes, a slight play in the nearside front wheel bearing, a worn offside rear drive shaft joint, and a minor exhaust manifold leak. The subsequent pass in September 2025 suggests these specific defects were addressed, indicating the previous owner maintained the car adequately rather than allowing faults to fester. Covering roughly 3,756 miles annually, this 1996 XJS has accumulated low mileage for its age. The odometer moved just 113 miles between the September 2023 test at 110,907 miles and the August 2024 test at 111,020 miles, suggesting the car sat stationary for extended periods or saw very light use during that year. From August 2024 to September 2025, the mileage increased by 1,651 miles, reflecting slightly more regular use recently. Low annual mileage often preserves consumables, yet prolonged standing can cause seals to dry out and brake discs to suffer surface corrosion. The recent uptick in usage is a positive sign, ensuring the drivetrain receives regular lubrication and exercise. Despite the clean September 2025 result, a buyer must inspect the undercarriage thoroughly. The August 2024 failure noted brake pipe corrosion obscured by grease or other material. This raises concerns about the overall condition of the hydraulic system and structural integrity beneath the vehicle. Probe the underside for deeper corrosion, particularly around the suspension mounting points and chassis rails, as a 1996 vehicle is highly susceptible to rust if not protected. The tester also flagged a slight play in the nearside front wheel bearing and a worn offside rear drive shaft joint in 2024. While the 2025 pass confirms these were fixed or resolved, examine the driveshaft gaiters and wheel bearings for fresh leaks or play during a test drive. Finally, check the exhaust manifold for signs of gas leakage or black soot stains, as the previous minor leak could have worsened under thermal cycling.
