- Reliability (3)The 2006 model is more robust than earlier W203 versions, but early M272 V6 engines are known for potential balance shaft gear issues that can be costly to repair.
- Maintenance (2)Ownership costs are high due to the requirement for premium fuel, synthetic oil, and the relatively high price of specialized European replacement parts.
- Technology (3)While the Harman Kardon audio system is a highlight, the COMAND infotainment system is difficult to navigate and the cabin tech feels very dated by modern standards.
- Comfort (4)The interior features high-quality materials and well-bolstered sport seats that offer excellent support, though the rear cabin remains somewhat cramped for taller passengers.
- Dynamics (4)The 2.5L V6 engine and sport-tuned suspension provide a smooth and balanced driving experience with sharp handling, though it lacks the raw acceleration of the C350.
