2005 Mercedes ML 2.7L Diesel · NA05 SFN

The vehicle remains roadworthy but the maintenance history indicates a worsening trend regarding deferred repairs and escalating structural degradation. The most recent test in May 2025 at 164,165 miles showed a pass despite an active oil leak and four tyres worn to the legal limit. While the vehicle continues to pass, the presence of corrosion on the rear lower chassis and pitted rear brake discs suggests that mechanical components are entering a phase where age-related wear is overtaking basic upkeep. At 164,165 miles over 21 years, the vehicle has averaged approximately 7,800 miles per year, which is consistent with typical light usage for an older SUV. The record shows consistent annual testing with roughly 15,000 miles covered between May 2024 and May 2025, and another 33,000 miles between March 2022 and May 2024. This steady mileage suggests the car has not sat for long periods but has placed consistent load on rubber components and suspension assemblies. A buyer must prioritize a thorough inspection of the chassis and brake-related mounting points. The 2022 test flagged corrosion on the front brake pipes, while the 2025 test identified corrosion on the rear lower chassis near a mounting. These areas require close monitoring for structural thinning that progresses beyond surface rust. Furthermore, the previous report of steering rack free play and inner joint play in 2022 necessitates a road test to ensure the steering geometry hasn't deteriorated further since the last inspection. The recurring issues with tyres in both 2024 and 2025 indicate a pattern of only replacing consumables when they reach failure limits. The oil leak noted in 2025 and the previously misted front shock absorber from 2022 suggest that engine seals and suspension dampers are beginning to fail. Given the pitted condition of the rear discs, the buyer should verify that the braking system is not binding and consider that components are likely nearing their next major service interval.
