2016 Jaguar XJ 3.0L Diesel · WJ 5879

The Jaguar XJ has successfully passed its most recent MOT on 3 August 2026, following an initial failure earlier that same day due to structural integrity issues with both rear tyres. While the vehicle currently holds a valid test certificate, the presence of dangerous defects involving tyre sidewall failure indicates a period of neglect regarding the condition of critical consumables. Aside from this specific event, the vehicle has maintained a clean MOT record throughout late 2024 and 2025, suggesting that the underlying mechanical health of the drivetrain and chassis remains stable and well-maintained by previous keepers. With a total of 63,922 miles over a ten-year lifespan, the vehicle averages approximately 6,400 miles per annum, which is well within the expected range for a luxury saloon of this calibre. This usage profile is generally favourable, as it avoids the excessive wear associated with high-mileage fleet vehicles while preventing the severe mechanical stagnation often seen in cars that sit idle for years. However, you should verify the service history to ensure that maintenance has been performed on a calendar basis rather than solely by mileage, as low-usage vehicles still require regular oil changes, brake fluid flushes, and coolant replacements to prevent internal degradation. When inspecting the vehicle, you must confirm that the rear tyres were replaced with high-quality, matching rubber rather than budget alternatives, as the XJ relies heavily on its suspension geometry and tyre contact patch for its signature ride quality. During your test drive, listen intently for any knocking or clunking sounds from the suspension over uneven surfaces, which could indicate worn-out bushes or ball joints, common wear points for a vehicle of this weight. Additionally, perform a sharp braking test from a moderate speed to check for any shuddering through the pedal or steering wheel, which would signify warped brake discs or seized calipers resulting from the vehicle having been parked for extended periods. Given the age of the vehicle, perform a thorough physical inspection of the brake discs for excessive surface corrosion or a lip on the outer edge, as these components often deteriorate through oxidation when a car is not driven daily. Check the battery health and the electrical systems, as the sophisticated onboard electronics in the XJ are highly sensitive to voltage fluctuations. Finally, inspect the underside of the vehicle for signs of oil misting or fluid leaks around the engine and transmission, and ensure that the service book reflects consistent, professional maintenance, as the complexity of the Jaguar drivetrain demands precise care to avoid costly long-term mechanical failures.
