2007 Mercedes-Benz CLS 3.0L Diesel · AC55 SAY

The maintenance trend for this 2007 Mercedes-Benz CLS remains stable, with the most recent MOT on 5 October 2024 recording zero defects at 154,404 miles. The vehicle passed cleanly, indicating no immediate mechanical or structural failures at that time. Given the current date of July 2026, the MOT certificate has expired, meaning the car currently lacks a valid roadworthiness certificate. The previous test on 1 June 2023 also passed without advisories, though a failed test on 23 May 2023 at 129,233 miles presents an anomaly, as no defects were recorded for that failure. This suggests an administrative or procedural failure rather than a mechanical breakdown. The lifetime average of roughly 8,127 miles per year appears low due to earlier sedentary periods, but recent usage tells a different story. Between the May 2022 test at 105,667 miles and the May 2023 test at 129,233 miles, the car covered 23,566 miles in a single year. This high accumulation continued, adding another 24,416 miles by October 2024. Such rapid recent mileage accumulation accelerates wear on consumables, suspension bushes, and drivetrain components, contrasting sharply with the vehicle's earlier, lighter use. Despite the clean MOT record, the high recent mileage and expired certificate necessitate a thorough physical inspection. A buyer must inspect the structural integrity of the underbody, paying close attention to corrosion on suspension mounting points and subframes, common issues on older premium vehicles that have covered high mileage. The condition of the brake discs and pads requires verification, as high-mileage driving accelerates wear beyond typical age-related deterioration. Suspension bushes and coil springs will likely exhibit fatigue from the heavy recent use. Tyre tread depth and uneven wear patterns should also be checked, as the rapid mileage accumulation suggests the car has been driven extensively, potentially compromising alignment and consumable lifespan.
