I bought the E320 through USAA buying service through a professionally run dealership-American Service Center- Alexandria, VA. I impressed by the cars looks, engineering, fuel economy, and the torque of the turbo-diesel--it gets up and goes. The quality of the car and its materials are evident. While the controls are well-place and intuitive, this is not the case in the Command/NAV interface. In particular, the voice commands do not measure up to the technology in less expensive Japanese and Korean cars. The USAA buying service combined with Mercedes incentives made the car more affordable- -a once in a life time purchase--maybe not. I love this car.
The torque and fuel economy delivered by the BLUETEC Turbo-Diesal Engine. The high quality vinyl seats, the Hardon Karmon Sound system, the total top sunroof, the beautiful design, and apparent quality and engineering that went into this car.
The Command/NAV interface is limited and not intuitive as the review reads. Hyundai Genesis voice commands and interface are more advanced in technology. I think German engineering needs to take lesson from the Japanese and Koreans on this.
