2004 Jaguar XJ 3.0L Petrol · R77 PBJ

This Jaguar XJ has maintained a consistent roadworthiness record over the past five MOT cycles, with all tests passing without defects or advisories up to the most recent examination on 2026-02-23 at 128,282 miles. The absence of any recurring issues or advisories across these intervals suggests the vehicle has been subjected to either diligent maintenance or benign operating conditions. However, the lack of recorded defects does not preclude the need for a thorough independent inspection, particularly given the vehicle’s age and the critical components that are not routinely tested under standard MOT procedures. The recorded mileage of 128,282 miles over 22 years equates to an average of approximately 5,831 miles annually, which is unusually low for a vehicle of this age. The most notable gap in testing occurs between the 2023-01-30 test at 114,736 miles and the 2024-03-06 test at 116,126 miles—a span of nearly 14 months with minimal mileage accumulation. This suggests prolonged periods of inactivity, which could exacerbate issues such as tyre degradation, suspension stiffness, or corrosion development. Conversely, the consistent passing of MOTs without advisories implies that no major mechanical failures were reported during these intervals, though this does not account for non-MOT-related wear such as fluid leaks or internal drivetrain deterioration. Given the vehicle’s age and the low mileage pattern, a prospective buyer should prioritise an inspection of the suspension system, particularly the condition of coil springs, bushes, and dampers, as prolonged standing can lead to stiffness or perished components. The braking system warrants close examination, including rear caliper binding (a common issue in older Jaguars) and the integrity of brake discs and pads, as wear patterns may not have been fully assessed in the absence of MOT defects. Structural integrity should also be scrutinised, focusing on underbody corrosion—especially around the sills, subframe, and exhaust mounts—where moisture accumulation during storage could accelerate deterioration. Finally, the electrical system, including battery health and wiring integrity, should be checked, as prolonged inactivity can compromise these elements.
