2007 Mercedes-Benz CLS 3.0L Diesel · SW07 LHA

The vehicle currently holds a valid MOT, but the maintenance history reveals a trend of reactive rather than proactive repairs. While the most recent test in March 2025 at 197,531 miles passed with only a minor lighting defect, the preceding failure in February 2025 indicates significant engine health issues. The persistence of an exhaust gas leak and high emission readings across multiple tests between 2024 and 2025 suggests that the previous owner only addressed exhaust issues when strictly necessitated by a test failure. At 197,531 miles, this 19-year-old Mercedes averages approximately 10,400 miles per year, which is consistent with typical long-distance use. The data shows a significant period of activity between March 2023 and February 2024, where the vehicle covered over 15,000 miles in just eleven months. This rapid accumulation explains the frequent wear noted on consumables and suspension components. The high mileage suggests the vehicle has been used regularly, but it also places considerable stress on the internal combustion engine and complex drivetrain components. A buyer must conduct a thorough inspection of the exhaust system and emissions hardware, as the recurring leaks and failures point to potential carbon buildup or a failing oxygen sensor. The suspension also requires close scrutiny; the 2023 record flagged play in the front ball joints and reduced damping in the rear shock absorbers. Given the uneven tyre wear noted in 2024, a professional should check for tracking alignment issues or worn control arm bushings that could lead to premature tyre degradation at this mileage.
