2006 Mercedes-Benz CLS 3.5L Petrol · PX06 AJU

The Mercedes-Benz CLS in question demonstrates a stable roadworthiness trend over the past eight years, with every MOT test—including the most recent on 18 May 2023—resulting in a clean pass without any defects or advisories. The vehicle’s compliance with all mandatory checks suggests no recurring mechanical failures, though the absence of advisories does not preclude underlying issues requiring inspection. The last test occurred just over three years ago, which is beyond the DVSA’s recommended annual interval for vehicles of this age and complexity. Given the low mileage at the time (24,594 miles), this gap raises questions about whether the vehicle was driven regularly or stood unused, potentially accelerating wear on fluid systems or suspension components. The recorded mileage of 24,594 miles over nearly 20 years equates to an exceptionally low annual average of around 1,230 miles, far below industry benchmarks for a vehicle of this age. The consistency in mileage increments—ranging from 143 to 264 miles between tests—indicates minimal usage, which could imply prolonged periods of storage. While low mileage generally correlates with reduced wear, it also suggests potential neglect in areas like battery health, tyre pressure monitoring, and fluid changes. The longest gap between tests was between 2018 and 2021 (2.5 years), during which the mileage only increased by 264 miles, further supporting the likelihood of limited driving. Given the clean MOT history, the primary focus for an in-person inspection should centre on components prone to deterioration in low-mileage, long-stored vehicles. The suspension system—particularly coil springs, bushes, and dampers—should be examined for dryness, corrosion, or perished rubber, as prolonged inactivity can accelerate degradation. Brake discs and calipers warrant scrutiny for binding or uneven wear, while the exhaust system should be checked for rust penetration or cracked heat shields. The battery, given the irregular driving pattern, may require testing for residual capacity, and the interior should be inspected for signs of moisture damage or mould, which often develop in poorly ventilated storage environments. While the MOT record offers no red flags, these areas demand thorough attention to confirm the vehicle’s true condition.
