2007 Mercedes CLS 3.0L Diesel · YEO 51N

The vehicle remains roadworthy, but the maintenance history reveals a worsening trend regarding the braking system and suspension components. While the most recent test in June 2026 at 72,200 miles passed, the tester identified new issues including a transmission oil leak and a binding nearside rear brake. The persistent presence of corroded brake pipes and deteriorating hoses, which have appeared in nearly every test since 2022, suggests that the previous owner has been treating systemic corrosion rather than performing comprehensive preventative repairs. At 19 years old, the recorded mileage of 72,200 miles is exceptionally low, averaging approximately 3,800 miles per year. This low usage pattern explains the significant age-related degradation of rubber components rather than mechanical wear from distance. There is a notable gap in mileage between February 2023 and June 2024, where the car covered over 8,000 miles, followed by a more consistent increase thereafter. The long periods of potential inactivity likely contributed to the perishing of tyres and the cracking noted in the 2022 record. A buyer must conduct a thorough inspection of the front suspension, specifically focusing on the nearside and offside front lower arm ball joints. The record shows severely deteriorated dust covers flagged in both 2024 and 2025, indicating these components have not been replaced despite repeated warnings. The distorted offside rear road wheel noted in 2024 and again in 2026 should also be checked for structural cracks that could cause vibrations at higher speeds. The braking system requires immediate attention. The recurring corrosion on the brake pipes and the deterioration of the rear hoses indicate a high risk of future failure if the lines are not replaced or treated. The binding nearside rear brake reported in the 2026 test suggests a sticking caliper or seized slider pin that needs investigation. Furthermore, the transmission oil leak identified in the latest test must be monitored closely to determine if it is a minor seal failure or a more costly internal fault.
