Our Verdict
A highly recommended purchase for those seeking a luxury grand tourer. This specific grey CLS 450 boasts an exceptionally clean MOT record and a consistent maintenance profile.
When inspecting this vehicle, prioritise the service history to ensure the 3.0L engine has had regular oil changes, as this is critical for long-term reliability in high-performance Mercedes engines. Given the luxury specification of the CLS 450, check that all electronic driver aids and interior features are functioning correctly, as these can be costly to repair out of warranty.
Negotiate based on the remaining tread depth of the tyres. While the MOT history shows previous issues with front tyre wear and sidewall damage in 2022 and 2023, the most recent tests were clean; however, high-performance tyres for this model are expensive replacements.
Owning a CLS 450 involves significant running costs due to the 2999cc engine. Fuel consumption will be high, particularly in urban environments, and the vehicle will sit in a higher CO2 tax bracket compared to smaller executive cars.
Insurance groups for the CLS 450 are typically high, reflecting its value and power. Maintenance costs are standard for the Mercedes-Benz premium range, where genuine parts and specialised labour rates apply.
Focus your inspection on the tyres and wheel rims. The MOT history from November 2022 and November 2023 specifically noted issues with the offside and nearside front tyres, including sidewall damage and edge wear. Ensure the current set is premium quality and correctly aligned to prevent a recurrence of these issues.
Additionally, perform a thorough check of the brake pads and discs. While not flagged as defects in the recent MOTs, the mileage (67,436) is reaching a point where wear-and-tear items on a heavy luxury vehicle may require attention.
This 2018 Mercedes-Benz CLS 450 is in excellent condition, having passed every MOT since 2021. With a current mileage of 67,436 miles, it has been used moderately and shows no signs of chronic mechanical failure. The lack of major advisories or failures in the last two years suggests a well-maintained example of this 3.0L petrol executive saloon.
Aggregate data is unavailable for this specific model, but the individual history of this vehicle suggests a high standard of care and reliability.
