2005 Mercedes-Benz CLK 3.2L Petrol · AD55 ALO

The most recent MOT tests on this 2005 Mercedes-Benz CLK, conducted just eight months ago on 24 September 2025, reveal an unusual but ultimately stable pattern: the vehicle passed one test and failed the next at identical mileage, yet no defects were recorded in either instance. This suggests either a rare administrative anomaly in the DVSA system or a vehicle that, despite its age, has not encountered any recurring mechanical or structural issues during the last two test cycles. The absence of advisories or repeated failures on the same components implies that, for now, the car has not exhibited any progressive wear patterns that would warrant immediate concern. However, the double-testing at the same mileage does warrant scrutiny, as it deviates from standard practice and may indicate an oversight in the testing process. The mileage progression over the past two years shows a consistent but moderate accumulation, averaging around 3,400 miles per year between the October 2023 and September 2025 tests. This rate is typical for a vehicle of this age, though the lack of intermediate tests—such as those required annually for vehicles over six years old—makes it difficult to assess whether maintenance was conducted between MOT cycles. The most notable gap is between the November 2024 and September 2025 tests, where the vehicle accumulated roughly 7,800 miles in just eight months, a rate that could imply either active use or prolonged periods of neglect. Without service records, it is impossible to confirm whether critical components like suspension bushes, coil springs, or brake calipers were inspected or replaced during this period. Given the absence of recorded defects, a prospective buyer should prioritise a thorough inspection of high-wear areas that are not routinely captured in MOT tests. The suspension, particularly the rear bushes and coil springs, should be examined for excessive play or corrosion, as these components often degrade silently over time. Binding brake calipers or unevenly worn brake discs—common issues in older Mercedes models—must be checked, as should the structural integrity of the chassis and sills for signs of rust or frame distortion. Additionally, the exhaust system should be inspected for leaks or excessive corrosion, particularly around flanges, as this is a frequent failure point in vehicles of this age. The double-testing anomaly suggests verifying the vehicle’s history for any unreported repairs or modifications that may not have been disclosed.
