2002 Mercedes Benz CL55 Mercedes 5.5L Petrol · AT51 AFJ

Structural integrity and suspension health represent the primary areas of concern for this vehicle, as evidenced by the most recent MOT test on 6 December 2022. The record identifies a clear degradation in the chassis-related components, specifically noting light oil misting on the offside front shock absorber and a severely deteriorated nearside rear constant velocity boot. Given that this inspection occurred nearly four years ago, the absence of a more recent test record creates a significant information gap regarding the current state of these components, making it impossible to verify if these defects have been rectified or if they have progressed into critical failures. With an odometer reading of 149,228 miles accumulated over 24 years, the vehicle has averaged approximately 6,218 miles per annum. While this aligns with typical usage expectations, the lack of MOT data since late 2022 suggests a prolonged period of inactivity or an extended off-road status. Mechanical systems on a vehicle of this complexity, particularly the hydraulic suspension and drivetrain, are susceptible to seal hardening and fluid degradation when left stationary for long intervals. Prospective buyers must account for the high probability that rubber components, seals, and bushings have perished further during this dormant period, regardless of the recorded mileage. During a test drive, pay particular attention to the offside front suspension. Listen for any knocking or clunking sounds when traversing uneven surfaces, which would indicate that the misting shock absorber has lost its damping efficiency. The vehicle should be tested for excessive body roll or erratic handling, as the hydraulic system is prone to leaks that can compromise ride height and stability. If the car exhibits a harsh ride or fails to level itself correctly upon startup, this points to a failure in the suspension architecture that will require expensive specialist intervention. The nearside rear constant velocity boot, flagged as severely deteriorated, must be inspected for signs of grease spray on the inner wheel rim or suspension arm. A torn boot allows road grit and moisture to contaminate the joint, which typically manifests as a rhythmic clicking or grinding noise during acceleration or tight cornering. Before committing to a purchase, it is essential to perform a cold-start inspection to check for any fluid pooling beneath the chassis and to verify that the vehicle reaches its operational ride height without delay. Given the significant time elapsed since the last recorded test, a comprehensive pre-purchase inspection by a technician familiar with the CL55 platform is strongly advised to assess the current condition of the subframe and hydraulic lines.
