2003 Mercedes ML 3.2L Petrol · C2 THA

The vehicle presents a concerning roadworthiness profile characterized by a trend of recurring mechanical and structural degradation. While it passed its most recent test in July 2025 at 115,986 miles, the tester identified new nearside play in the steering rack inner joints alongside corroded brake pipes obscured by grease. These findings indicate a failure to address underlying corrosion issues that were flagged in previous years. The maintenance trend is worsening, as critical faults related to the steering and braking systems continue to reappear despite the passing results. The mileage history is highly irregular for a twenty-three-year-old vehicle, recording only 115,986 miles which averages to approximately 5,000 miles per year. There is a significant seven-year gap between the October 2012 and October 2019 tests during which the car covered only 18 miles. This extreme inactivity suggests the vehicle sat for long periods, which often leads to the degradation of rubber components, seals, and fluid surfaces. Such stagnant use typically accelerates the corrosion of brake lines and suspension components due to lack of moisture displacement and friction. A buyer must conduct a rigorous physical inspection of the braking system and chassis integrity. The record shows a persistent issue with corroded brake pipes dating back to 2012, with the 2025 test noting these pipes were covered in grease, a practice that often suggests an attempt to hide structural rust from the tester. The steering rack inner joints have previously failed for play, and the recent report of nearside play indicates the steering geometry is nearing mechanical failure. Given the history of warped brake discs and fluctuating pedals, the entire braking hydraulic system should be evaluated for leaks and thinning to ensure the vehicle remains safe.
