2015 Mercedes-Benz ML 2.1L Diesel · M123 ABN

This Mercedes-Benz ML has demonstrated a remarkably clean MOT history over its recent testing cycle, with the most recent February 2026 inspection at 68,941 miles showing no defects whatsoever. The trend is stable and positive, as every test since at least 2018—including the February 2025 and January 2024 checks—has also passed without advisories or failures. The absence of recurring issues suggests the vehicle has either been consistently well-maintained or, alternatively, has been driven lightly enough to avoid common wear points. For a vehicle of this age and mileage, such a pristine record is unusual, particularly given the ML’s reputation for higher maintenance demands compared to many mainstream SUVs. The mileage accumulation reflects a pattern of very light use, with just over 6,200 miles per year since 2015—a figure well below the UK average for a vehicle of this age. The gap between the 2019 and 2024 MOTs (nearly five years) is particularly striking, during which the odometer rose by only 8,646 miles, indicating prolonged periods of minimal use or storage. This could imply the car has spent significant time off the road, which may have contributed to the lack of wear in critical systems. However, it also raises questions about fluid condition—oils, brake fluid, and coolant—all of which degrade over time even when a vehicle is not driven. The most recent 7,534-mile jump between the 2024 and 2026 tests suggests a slight uptick in activity, though still far below average. Given the complete absence of MOT advisories or defects, there are no obvious red flags for a buyer to prioritise beyond standard pre-purchase checks. That said, the long periods of inactivity warrant closer scrutiny of fluid levels and condition, particularly engine oil, differentials, and brake fluid, which can break down or absorb moisture when a vehicle sits idle. Suspension components—such as bushings, coil springs, and ball joints—should be inspected for dryness or stiffness, as these can degrade even with minimal mileage. The brakes, while never flagged, should be tested for binding or uneven wear, especially if the car has been driven infrequently, as moisture ingress can accelerate corrosion in calipers or discs. Structural integrity, including sills, wheel arches, and underbody panels, should also be examined for signs of corrosion, given the ML’s aluminium-intensive construction, which can still succumb to surface rust in certain conditions.
