The midsize 2006 Ford Fusion sedan comes in three trim levels: S, SE and SEL. The base S rides on 16-inch wheels and includes air conditioning, an MP3-compatible CD stereo with four speakers, a split-folding rear seat, cruise control, full power accessories and keyless entry. The SE adds a six-way power driver seat, audio controls on the steering wheel, carbon trim on the center console and dash, and two more speakers for the audio system. Options on the SE include alloy wheels, leather seats, a moonroof, an upgraded eight-speaker stereo and an in-dash CD changer.
