2003 Mercedes-Benz ML 2.7L Diesel · LL03 HUH

The vehicle most recently passed its MOT on 20 September 2025, but the overall maintenance trend is concerning. The history reveals a pattern of reactive repairs rather than preventative care, highlighted by repeated failures of the parking brake in both 2023 and 2025, with the latter being classified as a dangerous defect. Furthermore, there is a persistent advisory regarding the corrosion of the offside front brake pipe that has appeared on every test since July 2023, suggesting that the underlying issue is being managed with temporary measures rather than a permanent replacement of the line. With a recorded mileage of 142,435 miles over 23 years, the vehicle has averaged approximately 6,193 miles per year. This is a typical usage rate for its age, indicating the car has been used regularly rather than left to stand for long periods. While the mileage is moderate, the age of the vehicle means that rubber components, such as suspension bushings and engine mounts, are likely degraded due to time and environmental exposure. Prospective buyers should expect significant wear on all consumables and drivetrain components consistent with a two-decade-old luxury SUV. Detailed attention must be paid to the braking system and front-end geometry. The recurring brake pipe corrosion is a significant red flag; you should physically inspect the offside front line for pitting, scaling, or evidence of sealant being used to mask rust. During a test drive, ensure the parking brake holds the vehicle firmly on a gradient and that there is no shuddering under braking. The recent advisories for inner tyre wear on both front wheels are a strong indicator of incorrect wheel alignment or worn suspension bushes. Listen for clunks or knocks when turning the steering wheel or driving over uneven surfaces, and check the inner tread depth for uneven wear. Beyond the MOT defects, the repeated mention of windscreen damage and a recent nail in the tyre suggest a lack of meticulous ownership. You should verify the service history for evidence of timely automatic transmission fluid changes and coolant flushes, which are critical for the longevity of this specific model. Conduct a thorough underbody inspection for structural corrosion, particularly around the chassis rails and suspension mounting points. Finally, check the condition of the 12V battery and inspect all fluid levels for signs of contamination or degradation, as calendar-based wear is as significant as mileage on a vehicle of this vintage.
