The Mercedes-Benz CLS in question presents a clean and stable MOT history, with the most recent test on 29 October 2025 at 108,353 miles showing no defects—an outcome repeated across all five recorded examinations since November 2021. This consistency suggests the vehicle has undergone regular and effective maintenance, with no signs of deteriorating mechanical or structural issues. The absence of advisories or failures over this period indicates that major components—such as brakes, suspension, steering, and exhaust systems—have been well-maintained or replaced proactively. For a vehicle of this age and mileage, such a flawless record is uncommon and implies either meticulous ownership or a history of timely servicing by a professional. That said, the lack of recorded advisories could also mask minor wear that hasn’t yet reached MOT thresholds, meaning a buyer should treat this as a baseline rather than absolute assurance of long-term reliability.
The mileage accumulation of approximately 7,224 miles per year aligns closely with the average for a 15-year-old vehicle, suggesting neither excessive nor negligible use. The intervals between tests are standard, with roughly 3,500–4,500 miles covered annually, which is typical for a well-maintained car. There are no red flags in the spacing—no sudden jumps in mileage that might indicate neglect or rapid deterioration, nor are there prolonged gaps that could imply storage or disuse. The steady progression from 89,965 miles in November 2021 to 108,353 miles in October 2025 reflects predictable wear, though it does not provide insight into whether the car has been driven primarily in urban, motorway, or mixed conditions.
Given the absence of recorded faults, a buyer should prioritise a thorough pre-purchase inspection focusing on components not routinely checked during MOTs. Pay particular attention to the suspension—specifically the condition of coil springs, anti-roll bars, and bushings—since these are prone to wear without necessarily failing an MOT. Check for any signs of binding or uneven wear in the brake system, including the condition of calipers, brake fluid condition, and disc thickness, even though the MOT history shows no issues. Structural integrity is another critical area; inspect for corrosion in wheel arches, sills, and underbody panels, as well as any signs of previous accident damage that may not have been recorded. Finally, verify the condition of the drivetrain, including the health of the timing belt (if applicable), differential fluids, and any signs of leaks or unusual noises from the gearbox or transfer case.
While the MOT history offers reassurance, the age and mileage of this CLS mean some wear is inevitable. A buyer should treat this as an opportunity to confirm what may not have been captured in the official records—particularly hidden corrosion, suspension fatigue, or internal fluid degradation. The clean test results are a strong starting point, but due diligence beyond the MOT is essential for a vehicle of this vintage.
