A new front spoiler (less complex in design), the grill has been widened slightly, adaptive lights (point to where you steer), a slight change to the eyelids, slightly wider and lower than 2003 and added some included options in some of the packages. Most mods are for the discerning eye and don't dominate the changes. I saw one on the road yesterday. A bit more muscular looking in my opinion. Next years changes are more akin to those of the new 5 series.
