I never thought I would own a Mercedes. I always felt they were and old person's car. This CDI as a lot of power. I drove from south Jersey to 20 miles from Georgia on one tank of fuel. I bet I could have made it to Georgia. I lease the car and the only way I will not buy it after the lease is if Mercedes puts that motor in its S class.
The fuel mileage. The ride is soft.
The Nav system. Put this engine in an S-class car. You will have a winner.
