Our Verdict
Proceed with caution due to the vehicle's age and high mileage, despite a surprisingly clean MOT record. While this 2006 CLS has been well-maintained in recent years, it remains a complex luxury vehicle that can become expensive to repair if components fail.
When inspecting this vehicle, prioritise a thorough test drive to check the 7G-Tronic automatic gearbox for smooth shifts, as these units can suffer from solenoid issues if the transmission fluid hasn't been changed regularly. Ensure the Airmatic suspension, if equipped, rises and lowers correctly without any warning lights on the dashboard.
Check the service history folder meticulously for evidence of swirl flap motor replacements and turbocharger health, as these are common failure points for the 3.0-litre diesel engine at this mileage. Negotiate the price if there is no proof of recent transmission servicing or suspension work, as these are the most likely areas to incur significant costs.
As a 3.0-litre diesel, this CLS falls into a higher tax bracket, and fuel economy will be modest by modern standards, likely averaging 30-35 mpg on a run. Insurance will be in a high group due to the vehicle's original value and performance, so obtain quotes before committing.
Maintenance is the biggest financial variable; while the MOT history suggests the car is currently in good condition, parts for a 2006 Mercedes-Benz are premium-priced. Expect to budget for more frequent servicing and potential 'age-related' repairs to keep the car roadworthy.
While the MOT history from 2018 to 2022 shows no defects, do not let this lull you into a false sense of security. Inspect the underside for any signs of corrosion on the subframes and brake lines, as these are common MOT failure points for Mercedes models of this era that may have been missed or recently cleaned.
Check all electrical features, including the COMAND infotainment system, electric seat adjustments, and door mirrors. These complex systems are prone to glitches as the vehicle ages. Finally, examine the condition of the tyres and brakes; at 146,000 miles, ensure that consumables are not due for immediate replacement.
This silver 2006 Mercedes-Benz CLS 320 CDI has covered over 146,000 miles, yet its recent MOT history is remarkably clean, showing five consecutive passes without a single recorded defect. It represents a high-specification cruiser that has clearly been looked after by previous owners. However, potential buyers should be aware that at 20 years old, the mechanical and electronic systems are nearing the end of their design life.
The first-generation CLS is known for high-quality engineering, though it is prone to issues with air suspension and complex electronic modules as it reaches this age.
