2006 Mercedes CLK 1.8L Petrol · SB06 ACF

The vehicle remains roadworthy, but the maintenance history indicates a worsening trend regarding corrosion-related components. While the most recent test in November 2025 at 98,548 miles passed, it identified a corroded nearside rear brake pipe and a minor exhaust leak. These issues represent a progression from the November 2024 test, where both front brake pipes and the nearside rear pipe were flagged for corrosion. The persistence of these faults suggests that while repairs are made to achieve passing, the underlying issue of oxidation is not being fully addressed. At 20 years old, the recorded 98,548 miles represent exceptionally low usage, averaging approximately 4,900 miles per year. The data shows consistent usage patterns, with roughly 2,000 miles being covered between each annual test from 2023 to 2025. This low-frequency-of-use profile typically results in less mechanical wear on the drivetrain and engine components. However, low mileage on a vehicle of this age often leads to accelerated degradation of rubber components and surface rust on metalwork due to lack of heat exposure. A buyer must conduct a thorough physical inspection of the braking lines and exhaust system. The recurring reports of corroded brake pipes across 2024 and 2025 indicate that the metal lines are thinning and failing. The nearside rear anti-roll bar ball joint noted for having play in 2024 should also be checked for further deterioration, as suspension bushings often perish when vehicles sit. Given the minor exhaust leak identified in 2025, the structural integrity of the exhaust manifold and hangers should be verified to ensure no significant structural rot is developing.
