2006 Mercedes-Benz CLK 2.1L Diesel · RJ56 CGF

The 2006 Mercedes-Benz CLK presents a stable and reassuring maintenance trend based on the available DVSA MOT records. The most recent test, conducted on 13 October 2021 at 140,620 miles, passed with zero defects recorded. This clean pass, following a failed test just five days prior on 8 October 2021 at 140,605 miles (also with no defects recorded, suggesting a retest after a minor or procedural issue), indicates the vehicle was in sound mechanical and structural order at that time. However, a significant gap exists in the record. No MOT entries exist between October 2021 and the current date of June 2026, a period of nearly five years. This absence of recent certification means the current roadworthiness status is entirely unknown, and the stable trend cannot be confirmed beyond late 2021. The mileage pattern reveals a notable anomaly that warrants scrutiny. Between the November 2020 test (129,948 miles) and the October 2021 test (140,620 miles), the vehicle accumulated 10,672 miles in under twelve months, a sharp increase compared to the prior annual average of approximately 13,739 miles between 2019 and 2020. More critically, the recorded mileage has remained static at 140,620 miles since October 2021. Given the vehicle's age and typical use, this five-year mileage plateau strongly suggests the car has been standing idle for extended periods or has been taken off the road. Prolonged static storage introduces its own risks, including deteriorated rubber components, stale fluids, and potential corrosion in brake lines and the exhaust system, which MOT records alone cannot capture. A buyer must approach this CLK with a thorough in-person inspection focused on the consequences of long-term storage. The undercarriage, sills, and subframes should be examined closely for structural corrosion, a common issue on older Mercedes models that can compromise integrity. All rubber suspension bushes, ball joints, and tyres should be checked for perishing and cracking, as tyre date codes will likely indicate aged rubber even if tread depth appears adequate. The braking system requires particular attention; calipers can seize and discs can corrode unevenly from standing. A full fluid service history is essential, as old brake fluid, coolant, and engine oil degrade over time regardless of mileage. The lack of recent MOT entries means no independent verification of safety-critical systems exists for nearly five years, making a pre-inspection by a qualified mechanic a necessity before any purchase.
