2005 Mercedes CLK 3.2L Gas bi-fuel · LM54 FPZ

The 2005 Mercedes CLK is currently roadworthy following its most recent MOT test on 2025-11-10, where it passed with only one minor defect: a severely deteriorated dust cover on the nearside front lower suspension arm ball joint. However, the maintenance trend shows a concerning worsening pattern, particularly in the suspension and lighting systems. The same vehicle failed the previous MOT on the same day due to multiple issues, including headlamp aim problems and the same deteriorated ball joint cover, indicating unresolved or recurring faults. The vehicle has accumulated 100,214 miles over 21 years, averaging approximately 4,772 miles per year, which is relatively low for its age. This suggests the car has likely seen light use or periods of inactivity, potentially preserving mechanical components but possibly contributing to issues like seized suspension joints or corrosion in damp areas. The MOT history reveals a significant gap between the 2023-09-27 failure and the 2024-09-24 pass, during which the nearside front coil spring fractured and the offside lower arm ball joint became excessively worn. The 2025-11-10 test shows the same ball joint issue persisting, now with a deteriorated dust cover, indicating ongoing neglect or insufficient repair. Buyers should conduct a thorough in-person inspection focusing on the front suspension components, particularly the nearside lower arm ball joint and coil springs, as these have been repeatedly flagged. The deteriorated dust cover is a symptom of a potentially failing joint, which could lead to sudden failure if not addressed. Additionally, the recurring headlamp aim issues suggest possible alignment problems or damage to the reflectors, which may affect nighttime visibility. The corrosion on the offside front coil spring also indicates potential structural weakness in the suspension system, warranting close examination of the entire front suspension assembly for wear, rust, or binding components.
