Mercedes-Benz S550

the Mercedes S550 is the benchmark for luxury sedans. Editors say the S550 excels in offering all the prestige, comfort and technological features a luxury car owner would expect, and more. Its vast cabin is a cocoon of quietness, elegance and high-quality ambiance, reviews emphasize. Redesigned in 2007, the current S550 sedan continues with the new longer wheelbase and distinctive design. The big Benz's powertrain is a 382-hp V-8 engine matched with a seven-speed automatic transmission driving either the rear wheels or an optional AWD system, branded "4MATIC." Reviewers are surprised by the S-Class' quick acceleration and outstanding handling, often commenting that the Mercedes S550 drives like a much smaller sports sedan.

The Mercedes S550's interior design gets compliments for its refinement and quality materials, although many auto writers say the screen-based COMAND multi-function control system could be more intuitive and less complicated. Among the many available advanced features are an Active Body Control suspension, heated/ventilated seats with built-in massage function, and a Night View system which presents a view of the road ahead with an infrared camera. Reviews say one big drawback to the Mercedes S550 is its high price. Other lower-priced luxury cars mentioned as worthy alternatives include the Lexus LS 460 (*est. $62,900 to $72,900), the BMW 750i (*est. $76,800 to $79,900) and the Audi A8 (*est. $70,690 to $74,690).
