I was skeptical to buy a Mercedes, and felt it may be over priced, but it has been worth the money. Compared to other high end manufacturers, Mercedes drivers recieve the best overall performance and feel of a luxury car.
The sport version has so much room, I forget its kick other than the drive.
I would add toggle to the steering wheel for navigation like the radio feature.
