Our Verdict
A strong recommendation for those seeking a low-mileage luxury cruiser, provided the recent wheel issues have been fully resolved. The overall history is clean, though the September 2025 MOT failure suggests a period of neglect or a significant impact event.
Your primary focus should be the repairs carried out following the September 2025 MOT failure. The vehicle failed on three fractured road wheels and a structural tyre failure; you must verify if the wheels were professionally repaired or replaced with genuine Mercedes-Benz parts, as fractured alloys can be a safety risk.
Check the service history for evidence of regular oil changes for the 2925cc diesel engine. Given the low annual mileage, ensure the car hasn't spent too much time idling or doing only short trips, which can lead to DPF (Diesel Particulate Filter) issues common in larger diesel engines.
Owning a 2.9L diesel CLS involves significant costs. Expect high VED (road tax) due to the engine size and emissions bracket, and insurance will likely be in a higher group reflecting the car's value and performance.
Fuel economy will be respectable for long-distance cruising, but urban driving will see a sharp increase in consumption. Maintenance for the CLS is premium, with brake pads and tyres (as seen in the 2025 MOT) being expensive consumables.
Carefully inspect all four alloy wheels for any remaining cracks or signs of poor refurbishment, specifically referencing the 'fractured' failures noted in the 2025 MOT history. Check the offside front tyre for any bulges or uneven wear that might suggest a lingering alignment issue following the structural failure recorded.
Additionally, check the brake pad thickness on the front axle. Although the car passed the MOT shortly after the failure, it is worth confirming that high-quality pads were fitted rather than a budget alternative on a high-performance vehicle.
This 2018 white Mercedes-Benz CLS diesel has covered 55,754 miles, which is relatively low for its age. While it boasts a largely clean MOT record from 2022 to 2024, the most recent inspection in September 2025 revealed several structural issues with the wheels and tyres. Once these are confirmed as repaired, the car presents a compelling value proposition due to its low mileage and powerful 2.9L engine.
While aggregate data is unavailable for this specific model, the CLS generally maintains a reputation for high build quality and engine longevity.
