AI Market Summary

Diesel executive saloon with strong refinement, comfort, and highway cruising credentials — typical CLS strengths on longer journeys.
Median €44k is fair value for age and mileage within market; +15% year-on-year reflects stable demand for premium diesels.
DPF regeneration faults are the weak point here — budget €800–€1,500 for cleaning or replacement. AdBlue heater failures also common; inspect warning lights carefully.
Before buying, request full service history and ask specifically about DPF cleaning or replacement records; a blocked DPF is expensive to ignore.
Have a pre-purchase diagnostic scan run on the AdBlue heating system and fuel injectors — early warning of carbon buildup saves money later.

Strong safety specification including multiple airbags, ESC, and active collision mitigation
Proven OM654 2.0L diesel engine with good torque delivery and reliability track record
