Have been driving the R350 for a year now. Consistently getting 23-24 mpg with my daily commute at 70-75 mph. Great highway cruiser with good comfort (AC/Interior). Fold down seats work quite well. Car has had a crown steer pulling problem since new which they tell me to live with. MB nickel and dimes you on the options as well. Sliding rear doors and backup camera would be a big improvement as well as standard park distance (it is big and difficult to park).Decent value with $5000 incentive and Employee discount. Overpriced as compared to others in this segment. Great looking car with decent fit and finish.
Driveability, interior comfort, Good HVAC and radio.
Sliding rear doors. More options included. Bluetooth should be standard.
