2007 Mercedes-Benz ML 3.0L Diesel · JH57 AEH

The vehicle maintains a roadworthy status but the maintenance history shows a worsening trend regarding structural integrity and mechanical wear. The most recent test in July 2023 at 79,561 miles flagged a cluster of advisories including a stiff steering column UJ, deteriorated prop shaft coupling, and a marginal parking brake. While the vehicle passed, the accumulation of multiple mechanical-related advisories alongside previously noted sub-frame corrosion suggests the car is entering a phase where reactive maintenance is becoming the norm rather than proactive preventative care. The mileage profile is exceptionally low for a 19-year-old vehicle, averaging approximately 4,187 miles per year. There is a significant gap in usage between July 2020 and July 2021, where the car covered only 53 miles in a full year. While low mileage explains the relatively low wear on drivetrain components, it often correlates with accelerated degradation of rubber parts and increased corrosion. The record confirms the front sub-frame bushes perished by 2020, a common consequence of long periods of stationary despite the low annual mileage. A buyer must prioritise a thorough inspection of the underbody to assess the extent of the rust. The record notes structural corrosion on the integral body structure in 2022 and specifically the rear sub-frame in 2023; these areas require close monitoring as corrosion typically progresses to compromise structural rigidity. Furthermore, the braking system shows a history of issues ranging from binding rear calipers to thin pads and pitted discs reported between 2021 and 2023. The stiff steering column and deteriorating prop shaft coupling noted in July 2023 indicate impending mechanical failures that will likely require replacement to ensure vehicle handling and safety.
