2004 Mitsubishi Shogun 3.2L Diesel · YR04 AEZ

The latest MOT test on 18 February 2026 resulted in a pass with no recorded defects. When evaluating the overall maintenance trend, there is a visible pattern of the vehicle failing its initial test before passing shortly thereafter, as evidenced by the failures recorded in both early 2025 and early 2026. This suggests a reactive maintenance cycle where repairs are likely performed specifically to address MOT failure points rather than as part of a proactive, preventative service regime. While the vehicle is currently compliant, the history indicates that components are reaching the threshold of failure on an annual basis. The recorded mileage of 131,597 miles over 22 years represents an average annual usage of approximately 5,982 miles, which is significantly lower than typical for a vehicle of this class. While this lower mileage may suggest less internal engine wear and less strain on the drivetrain, it introduces specific risks associated with infrequent use. Vehicles that spend extended periods stationary are susceptible to age-related degradation that mileage alone does not capture, such as the perishing of rubber components, the stagnation of vital fluids, and the development of corrosion on various mechanical surfaces. Given the lack of recorded advisories, a prospective buyer must perform a rigorous physical inspection to identify issues that the MOT testing process may have missed. Closely examine the tyres for sidewall cracking or perishing, as rubber degrades over time even if the tread depth remains high. Inspect the brake discs for heavy surface corrosion or pitting and listen for any binding or shuddering during the test drive, which could indicate seized calipers or uneven pad wear from standing. You should also check the suspension for any signs of wear, specifically listening for clunks or knocks that would indicate perished suspension bushes or weakened coil springs. Furthermore, it is essential to verify that the vehicle has been maintained on a calendar-based service schedule rather than just a mileage-based one. Fluids such as brake fluid, coolant, and engine oil should be replaced according to time intervals to prevent moisture contamination and internal degradation. Inspect the chassis and sills for signs of structural corrosion, which can be exacerbated by moisture retention during periods of inactivity. Finally, check for any evidence of fluid leaks from the engine or transmission seals, which can shrink and fail when a vehicle is not driven regularly, and ensure the 12V battery is in good condition to avoid starting issues.
