- Reliability (3)While the W204 generation is sturdier than its predecessor, potential issues with the Electronic Ignition Switch (EIS) and subframe corrosion in salt-belt states require attention.
- Maintenance (2)Routine maintenance and parts carry the typical Mercedes-Benz premium, and specialized labor for the 4MATIC system can make repairs more costly than domestic or Japanese competitors.
- Technology (3)For 2009, the pop-up COMAND screen was innovative, but the system's interface and limited smartphone integration feel significantly aged by modern standards.
- Comfort (4)Cabin insulation is excellent and the front seats offer great long-distance support, though the rear seat remains somewhat tight for adult passengers.
- Dynamics (4)The Sport-tuned suspension and 4MATIC all-wheel drive provide a very planted and confident driving experience, though the 228-hp V6 lacks the punch of its larger-displacement rivals.
