1984 Jaguar XJS 3.6L Petrol · A412 YGL

The vehicle presents a stable maintenance trend, passing all three recorded MOT tests without any defects. The most recent test on 25 June 2025 at 2,148 miles resulted in a clean pass, indicating no immediate mechanical or structural failures at that time. However, this certificate is over a year old as of July 2026, meaning a fresh test is now due to confirm the current condition. The mileage history contains a severe anomaly that demands scrutiny. On 16 September 2022, the tester recorded 66,220 miles, yet by 25 April 2024, the reading had dropped drastically to just 35 miles before rising to 2,148 miles in June 2025. Such a regression is mechanically impossible without an odometer replacement or a recording error. Given the vehicle's age of 42 years and the current reading of 2,148 miles, the 2022 figure likely represents a clerical error or a disconnected instrument cluster. This discrepancy makes verifying the true mileage impossible without inspecting the car's service history and physical wear. Despite the clean MOT record, the extremely low recorded mileage of roughly 51 miles per year suggests the vehicle has spent prolonged periods stationary. A buyer must inspect for the ailments of dormancy rather than high mileage. Check the brake calipers for binding and the discs for surface corrosion from standing. Examine the rubber suspension bushes and tyres for perishing and flat-spotting, as old rubber degrades regardless of use. Inspect the fuel system for varnish or blockages from stale petrol and assess the cooling system for cracked hoses. The structural integrity of the underside requires close examination; low mileage does not preclude corrosion, especially if the car sat in damp conditions. Verify the odometer's condition and look for signs of tampering or replacement to resolve the conflicting mileage readings.
