These cars are expensive to buy and maintain, but it really is the best car on the road. I traded my 2000 S500 in on the '03 with 4matic. The 4matic tends to drag or hold back compared to my rear drive, but it is great in the rain and snow. The '03 update really changes the look of the car inside and out. Fuel economy is not much better than a Range Rover. I'm averaging about 15 mpg, and I do a lot of highway driving. My rear drive got much better fuel economy. My car also has the sport package which also changes the look of the car quite a bit. It was next to impossible finding a 4matic with the sport package in a good color, but they are out there. A great car to buy used, save a ton!
4matic all wheel drive. Sport package. The general look of the car. A big head turner.
Make Navi DVD based (this happened in '04) try to improve fuel economy on 4matic cars. eEven the wealthy want to get good gas mileage!
