2005 Mercedes-Benz CLK 1.8L Petrol · KX55 YOW

The vehicle is currently roadworthy but the maintenance history reveals a worsening trend regarding mechanical and electronic systems. While it passed its most recent test in March 2026 at 125,864 miles, this followed a significant failure just eight days prior. The record indicates persistent issues with the engine emissions system and safety equipment that have resurfaced across multiple years, suggesting that repairs are only being addressed reactively to pass inspections rather than as part of a preventative schedule. At 21 years old, the recorded mileage of 125,864 miles represents an average usage of approximately 6,000 miles per year. This low mileage suggests the car has been used sparingly, which often leads to the degradation of rubber components through age. Between June 2024 and March 2026, the vehicle covered roughly 8,000 miles, a relatively low interval. However, the failure of the front suspension arm ball joints and bushes in 2026 confirms that low mileage has not prevented structural rubber components from significant wear and age-related failure. A buyer must conduct a thorough inspection of the engine management and emissions system, as carbon monoxide and lambda sensor readings failed in both 2024 and 2026. These recurring faults point to potential fuel mixture issues or failing sensors that require diagnostic attention. The supplementary restraint system warning lamp appeared in both 2024 and 2026, indicating a persistent fault in the airbag deployment system that must be verified to ensure safety. Additionally, the oil leak noted in the March 2026 test should be monitored to ensure it does not escalate into a more significant failure.
