2006 Mercedes-Benz S-Class Sedan S500 4dr Sedan (5.0L 8cyl 7A)
The ride is velvety smooth and luxurious. I have never driven a car so comfortable, quiet, smooth shifting and excellent. The front and back have a large amount of roominess with all this comfort. It smeels of luxury. It has plenty of power, so when you want to go fast, it'll do it easily. It has 3 driving settings: Comfort, Sport 1 (firm driving) and Sport 2 (more firm driving) which makes it so much more fun.
Comfortable and luxurious seats. The wood and leather trimmed steering wheel. Massaging seats/cooled and heated seats. Very roomy inside.
Controls take time to learn. Navigation System is complicated - I had to ask the dealer 3 times to get me to basic use of the system.
