The 2007 Mercedes-Benz S550 is an all-new luxury sedan presenting the best the iconic German car manufacturer has to offer. Like previous generations of the S-Class line, the S550 coddles driver and passengers alike in luxurious surroundings, while taking electronic control over interior systems and driving aids to a new level., Front multicontour seats contain electronically adjustable air bladders and offer numerous massage settings in addition to heating and cooling controls and 14-way power positioning. The front seats also automatically adjust the side bolsters to grip the more zealous driver in heavy cornering., From the outside, the 2007 Mercedes-Benz S550 is slightly longer than its ancestors, with an extra 3 inches in the wheelbase. It also sports muscular wheel-arch bulges. Despite this nod to current car couture, the styling is still generally restrained, in keeping with the understated confidence the S-Class has long represented. Inside, soft leather and rich wood are complemented by indirect ambient lighting and quality switch gear.
