2006 Mercedes-Benz ML 3.0L Diesel · CJ 1678

The vehicle remains roadworthy, though the maintenance history reveals a persistent trend of developing structural degradation. The most recent test in November 2025 at 53,587 miles indicates a pass despite recurring advisories regarding corrosion on the inner sills and seat belt anchorages. While the tester did not find the rust excessive yet, the repeated nature of these warnings across five consecutive years suggests that the structural integrity is subject to environmental factors that require active monitoring to prevent future failure. The mileage profile is exceptionally low for a twenty-year-old vehicle, averaging approximately 2,679 miles per year. Between November 2021 at 47,891 miles and November 2025 at 53,587 miles, the car covered only 5,696 miles. This usage pattern suggests the vehicle has spent long periods stationary, which minimizes wear on drivetrain and engine components. However, low distance often correlates with the degradation of rubber components and accelerated oxidation, which aligns with the structural rust issues noted in the record. A buyer must prioritise a thorough physical inspection of the inner sills and the rear sub-frame. The 2022 test specifically flagged corrosion on the rear sub-frame and suspension mounting points, and while this was not weakened at the time, these areas are critical for vehicle safety. The recurring advisories for undersealing, under trays, and sill covers indicate that the previous owners were aware of the rust risk but the underlying issue remains present. You should verify the seat belt anchorage points for surface pitting to ensure the corrosion has not progressed beyond the levels noted by the MOT tester.
