2004 Mercedes-Benz CLK 1.8L Petrol · HS53 DCE

The Mercedes-Benz CLK in question presents a stable roadworthiness profile over the two most recent MOT tests, both conducted in April 2022 at an identical mileage of 115,997 miles. The vehicle passed its subsequent test just seven days later, suggesting any issues were either minor or swiftly rectified. With no defects recorded in either the failed or passed entries, there is no evidence of recurring mechanical failures or structural concerns. However, the absence of any advisories or warnings in the MOT history raises questions about whether the tester overlooked subtle wear—common in older luxury vehicles where cosmetic or non-critical components may be overlooked. The lack of recent testing (nearly four years since the last MOT) is the most pressing concern, given the vehicle’s age and the potential for undetected degradation in suspension, brake systems, or exhaust emissions. The mileage of 115,997 miles over 22 years equates to roughly 5,273 miles annually, which is unusually low for a vehicle of this vintage. Such low annual mileage often correlates with either infrequent use or prolonged periods of inactivity, both of which can accelerate hidden wear. The identical mileage figures across the two 2022 tests suggest the car may have sat unused between tests, a pattern that could exacerbate issues like seized bearings, degraded rubber components, or fluid degradation in the braking and cooling systems. Without further historical records, it’s impossible to confirm whether this has been a consistent trend or a recent development, but the stagnant mileage is a red flag for potential neglect. For a prospective buyer, the primary focus should be on components that deteriorate even with minimal use. The suspension—particularly the bushings, coil springs, and ball joints—should be inspected for stiffness or corrosion, as these are prone to failure when a vehicle remains stationary for extended periods. Binding or uneven brake performance, especially if the calipers or discs show signs of rust or uneven wear, would indicate neglect. The exhaust system, including the catalytic converter and oxygen sensors, should be checked for leaks or blockages, as these can cause emissions failures and are often overlooked in low-mileage vehicles. Additionally, fluid levels—brake, coolant, and power steering—should be verified, as stagnant fluids can degrade over time. Given the age of the vehicle, a thorough inspection of the bodywork for structural corrosion, particularly around wheel arches and underseal, is also advisable.
