2012 Mercedes-Benz ML 250 2.1L Diesel · KP12 JGZ

The 2012 ML 250 presents a stable and currently strong roadworthiness profile. The most recent test on 24 May 2025 at 138,721 miles passed with zero defects, a clean sheet that has now been repeated for two consecutive years. This indicates the vehicle is in sound mechanical order today, with no outstanding safety or emissions concerns flagged by the tester. Mileage accumulation sits at roughly 9,909 miles per year over fourteen years, which is typical for a large diesel SUV of this type. The record shows a notable jump of 14,114 miles between the May 2022 test at 100,103 miles and the May 2023 test at 116,930 miles, suggesting a period of heavier use or a return to regular long-distance driving after lighter prior years. Since then, the annual mileage has dropped sharply to around 7,677 miles per year, which may reflect a change in ownership or usage pattern. The 2022 test at 100,103 miles is the only entry with recorded defects, and it reveals a pattern worth noting. Both the offside rear and nearside front tyres were worn close to legal limits and worn on edge, pointing to uneven wear that could indicate suspension geometry issues, misaligned tracking, or simply neglected tyre rotation. Front and rear brake pads were also flagged as wearing thin at the same test, suggesting the vehicle was driven hard or used for towing during that period. All four items were rectified before the 2023 test, so the trend is resolving rather than worsening. A buyer should still inspect the front suspension bushes, track rod ends, and wheel alignment carefully, as the edge wear on both tyres hints at a possible alignment or damping issue that may have returned. The undertrays noted in 2023 remain worth checking for damage or fluid retention, particularly around the engine and transmission. Given the age and mileage, a thorough underside inspection for corrosion on subframes, brake lines, and exhaust mounting points is advisable, even though no structural defects have appeared on the record.
