How to differentiate from a 2006 and 2007 BMW X3?

The one I saw had metallic "bumpers" rather than the thick plastic ones does this mean it is the 2007? Or metallic bumpers where available for the 2006 before the facelift?How to differentiate from a 2006 and 2007 BMW X3?The 2006 x3 has full body color bumpers, the 2007 has the plastic piece running through it to break it up a bit. In 2007 if you want full body color bumpers, you'll need to get the sport package.
