2014 Mercedes-Benz CLS 3.0L Diesel · F1 AUR

The vehicle remains roadworthy but the maintenance history reveals a clear trend of environmental degradation due to long periods of inactivity. The most recent test in August 2025 at 33,966 miles identified corrosion across all four brake discs and both the offside front and rear brake pipes. While the vehicle passed, the persistence of structural corrosion on the rear sub-frame, which was flagged in multiple consecutive tests, indicates the car is susceptible to moisture-related damage from standing stationary. The mileage pattern is exceptionally low for a twelve-year-old vehicle, averaging approximately 2,830 miles per year. Data shows that between July 2022 at 33,840 miles and August 2025 at 33,966 miles, the car covered only 126 miles over three years. This extremely low usage explains the recurring pitting and scoring on the brake discs, as the components have not been used enough to clear surface rust, leading to oxidation- up on the metal surfaces. A buyer must prioritize a thorough physical inspection of the rear sub-frame to ensure the corrosion noted in 2024 and 2025 has not progressed toward structural thinning. The recurring reports of corroded brake pipes covered in grease suggest that previous owners may have masked leaks or ignored early signs of fluid line failure. Additionally, the long-term history of sidewall damage on tyres dating back to 2021 indicates that the rubber may be aging poorly or being treated roughly despite the low tread depth.
