2005 Mercedes-Benz CLS 3.0L Diesel · SA55 AJO

The vehicle presents a concerning maintenance profile characterized by recurring mechanical issues and a lack of recent testing. While the December 2021 test at 207,448 miles showed no defects, this record is now over four years old, leaving the current roadworthiness of the vehicle unverified. The historical data indicates a pattern of worsening deterioration between 2018 and 2020, where multiple failures regarding braking systems, suspension, and tyre integrity suggest a period of neglected upkeep. Although the 2021 result implies a clean slate, the long gap in documentation prevents a definitive assessment of the car's current condition. The mileage accumulation is consistent with a vehicle of this age, averaging approximately 9,878 miles per year. The record shows steady usage, moving from 100,347 miles in 2011 to 207,448 miles in 2021. There are no obvious signs of long-term stagnation, but the recent absence of MOT data since late 2021 is a significant red flag for any prospective buyer. The lack of recent testing means any developing faults in the drivetrain or chassis have not been professionally monitored for several years. A physical inspection must prioritise the braking system and fuel/brake lines. The records show a persistent trend of corroded brake pipes, specifically noted in 2017, 2019, and 2020. A buyer should check for fresh corrosion or signs of recent replacement on all brake lines and calipers. The history also highlights recurring issues with suspension bushes and lower arms, which failed or showed wear in 2019. Given the vehicle's age and mileage, the condition of the rear coil springs and shock absorbers should be scrutinised, as these components previously exhibited corrosion and casing damage. The engine's oil management requires close attention. Multiple tests between 2015 and 2020 flagged engine oil leaks or misting. While these were often described as slight, the cumulative effect on a high-mileage Mercedes-Benz engine can lead to significant issues. Finally, the history of uneven tyre wear on the inner edges suggests possible alignment or suspension geometry problems that may still persist. Any buyer should conduct a thorough underside inspection to check for structural rust and ensure that the previously noted oil leaks have been professionally rectified.
