2004 Mercedes-Benz E 3.2L Diesel · YJ54 ACH

The most recent MOT test conducted in December 2023 resulted in a pass with no recorded defects. Evaluating the overall maintenance trend, the vehicle appears to be stable. While the history shows two failures in 2021 and 2023, the absence of recorded defect details suggests these were likely minor, non-structural issues that were rectified promptly to achieve a pass. The consistency of the passing results without a buildup of recurring advisories indicates that the vehicle has been maintained to a standard that meets basic regulatory requirements without significant ongoing mechanical deterioration. The recorded mileage of 150,796 miles over a 22-year period represents an average annual usage of approximately 6,854 miles. This is a relatively low annual mileage for a vehicle of this age, suggesting it has not been subjected to the heavy mechanical strain of high-frequency long-distance commuting. While this lower usage typically means less wear on internal engine components and the drivetrain, it can also indicate periods of extended standing. Such usage patterns require a different inspection focus, as the primary concerns shift from mechanical wear to the degradation of components caused by age and inactivity. As the MOT history is notably clean of advisories, your physical inspection should prioritize age-related deterioration. Closely examine the tyres for any signs of perishing or sidewall cracking, which can occur even if the tread depth remains high due to the age of the rubber. You should also inspect the brake discs for excessive corrosion or pitting, a common symptom of vehicles that have been stationary for long periods, and listen for any signs of binding calipers or uneven braking during your test drive. Additionally, check the suspension bushes and coil springs for any signs of perished rubber or structural fatigue that may not yet have triggered an MOT failure. Finally, it is essential to verify the service history to ensure that time-based maintenance has been strictly followed. On a vehicle of this age, fluids such as coolant, brake fluid, and engine oil must be changed based on the calendar rather than just mileage to prevent internal degradation and corrosion. Inspect the engine bay for any evidence of weeping gaskets or fluid leaks from the shock absorbers. Given the potential for electrical issues in older Mercedes models, ensure a thorough check of the 12V battery health and all electronic auxiliary systems to ensure they are operating within normal parameters.
