2003 Mercedes S-Class 3.2L Diesel · S12 MAC

A pattern of long-term, consistent roadworthiness defines this vehicle, evidenced by a string of clean MOT certificates spanning several years. While the most recent test on 29 July 2026 resulted in a pass, it introduced the first recorded advisory in the recent history, noting slight play in the offside front lower suspension arm ball joint. This marks a transition from a period of zero recorded defects between 2022 and 2025 to the emergence of minor wear in the steering and suspension linkages, suggesting that components are beginning to show their age despite the lack of previous failures. The recorded mileage of 62,744 miles is exceptionally low for a vehicle of this age, representing an average annual accumulation of approximately 2,728 miles. This usage profile suggests the car has spent significant periods stationary or has been used only for very short, infrequent journeys. Mechanically, while this low mileage typically implies less cumulative wear on the engine, gearbox, and drivetrain, it can also mean that rubber components, such as suspension bushes and seals, may have undergone more age-related degradation than typical wear-and-tear would suggest. During a test drive, specific attention should be paid to the front end of the vehicle to monitor the condition of the offside front lower suspension arm. You should listen for any intermittent knocking, clunking, or clicking sounds when navigating uneven road surfaces or turning the steering wheel at low speeds, as these are classic symptoms of play in a ball joint. Additionally, because the vehicle has been driven so sparingly, it is prudent to check for any stiffness in the steering response or a slight pull to one side, which could indicate that the advised suspension play is progressing. Beyond the specific advisory, the lack of recorded defects over the last four years is a positive indicator of the vehicle's structural and mechanical stability. However, given the low annual mileage, you should also inspect the condition of all rubber hoses, belts, and various seals for signs of perishing or cracking that can occur when a vehicle is not regularly cycled through its full operating temperature range. Checking for any evidence of fluid weeping around the engine and transmission would be a sensible precaution to ensure that the low mileage has not resulted in dried-out seals.
