The new Mercedes Distronic Adaptive Cruise Control, with its two radar frequencies that sweep out 160 yards ahead, sounds a warning beep if it "thinks" the car is closing in too fast on an upcoming vehicle, and it is can break the vehicle up to 20 percent. The COMMAND? controller, which provides easy and convenient operation of the vehicle's systems, such as audio, climate control, navigation, multi-contour seat adjustments, telephone, and most of vehicle settings, replaces the iDrive system.

The interior is very plush with hand-fitted leather upholstery, head restraints, and center armrests. The steering wheel is trimmed with leather, while the dashboard, control console and doors are highlighted by hand-polished burl walnut. For sound control, the windows are made of double-insulated glass. The multi-adjustable and, yes, massaging seats have a wide variety of settings. The front seats have lumbar control and can be pre-programmed with three options. And the 600-watt Harman/Kardon surround-sound audio system defies description.

The S550 is two inches longer this year, measuring 205 inches. It is 58 inches high and tips the scale at 4,270 pounds. The base MSRP is $86,175, but with options added it can easily exceed $105,000. The S550 has a ton of features, which is indicative from its Tolstoy-like lengthy 700-page owner's manual. It's a good thing that it is not required reading before driving this beauty, right? But it is recommended reading.
