2007 Mercedes CLK 3.0L Diesel · WN07 YTW

The vehicle remains roadworthy but the maintenance history shows a worsening trend regarding structural integrity and mechanical wear. The most recent test in March 2026 at 202,848 miles introduced several new advisories that were not present in previous years. While the car passed, the appearance of play in the nearside front lower suspension arm ball joint and a minor exhaust leak at the backbox indicate that components are beginning to reach the end of their functional life simultaneously. The mileage pattern is remarkably consistent for a nineteen-year-old luxury coupe, averaging approximately 10,700 miles per year. Between March 2024 and March 2026, the vehicle covered 13,871 miles, representing a regular usage profile rather than long periods of inactivity. This consistent mileage suggests standard predictable wear and tear on rubber components and metalwork. The gap between the 2024 failure and the subsequent pass shows the owner addressed the immediate issues of tyre wear and lighting faults promptly after the initial failure. A buyer must conduct a thorough physical inspection of the rear sub-frame and suspension arms, as corrosion has been a recurring theme since at least 2023. The tester noted corroded sub-frames and suspension arms in both 2025 and 2026, and while currently described as not seriously weakened, the persistent nature of this rust suggests structural thinning is occurring. Specific attention should be paid to the front and rear brake hoses, where corrosion on the ferrule has been flagged in consecutive annual tests, which will eventually lead to hydraulic failure if not monitored.
