2008 Mercedes-Benz C 320 3.0L Diesel · LR08 PHZ

The vehicle remains roadworthy, but the maintenance history indicates a trend of worsening degradation regarding the braking and suspension systems. The most recent test in April 2024 at 128,880 miles identified a misting nearside front shock absorber and a non-excessive oil leak. While the car consistently passes its inspections, the recurring presence of corrosion and component component wear suggests that preventative maintenance has been deferred in favor of reactive repairs as parts reach failure thresholds. The mileage pattern is consistent with an eighteen-year-old vehicle, averaging approximately 7,160 miles per year. There is a notable gap in records between November 2020 and December 2021, where the car covered over 20,000 miles in just thirteen months. Since that period, usage has remained steady, with roughly 36,000 miles recorded since the 2020 test. This increase in annual mileage in the later years of the vehicle likely correlates with the accelerated wear of rubber components and metalwork seen in the recent advisories. A buyer must conduct a thorough physical inspection of the braking system and fluid lines. Corrosion on the brake pipes has been a persistent issue since at least 2016, appearing in almost every test from 2017 onwards. The tester specifically noted these pipes were covered in grease, which is a common tactic used to mask ongoing structural decay of the metal lines. Furthermore, the oil misting on the nearside front shock absorber requires immediate monitoring to ensure the leak does not progress to a total seal failure. The oil leak noted in the 2024 test also demands investigation to determine if it originates from a simple cover gasket or a more significant engine seal. Given the history of thin brake pads and worn tyres flagged in 2021 and 2023, the vehicle appears to have operated on the limits of consumable wear frequently. The presence of under-shields mentioned in earlier tests suggests that moisture accumulation on the underside of the car may have hidden structural rust on the chassis or mounting points, necessitating a visual check of the undercarriage.
