2006 Mercedes-Benz CLK 1.8L Petrol · EK56 FAF

The vehicle is currently roadworthy, but the maintenance history indicates a trend of developing structural and mechanical degradation. In the most recent test in November 2023 at 139,807 miles, the car passed only after addressing a failed offside front outer track rod end and a faulty windscreen washer system. While the immediate safety-critical failures were rectified, the persistence of structural corrosion on the rear chassis and exhaust suggests that the vehicle is battling ongoing age-related decay that has not been halted. At 139,807 miles, the CLK has averaged approximately 7,000 miles per year, which is consistent with typical light use for a premium coupe. However, there is a significant gap in recorded data between the April 2021 test and the November 2023 test, during which the car covered over 11,000 miles. This period of use, combined with the low annual mileage, explains the appearance of rubber component perishing, such as the cracking offside rear tyre flagged in 2023 and the wear noted in 2021. A buyer must conduct a thorough physical inspection of the structural integrity of the rear chassis and suspension mounting points. The tester has repeatedly flagged corrosion in the rear structure between 2020 and 2023, indicating that while rigidity remains for now, the rust is active and likely to progress. The non-excessive oil leak noted in 2023 also requires close monitoring to determine if it is a minor gasket seep or a more significant seal failure. Given the history of track rod end play and suspension corrosion, the entire steering geometry and bushings should be checked for perished rubber or excessive play before purchase.
