I don't think anyone has touched on this yet... The 2007 X3 apparently has a rear heated seat option, which was never offered before.
From BMWUSA.com (

"New styling touches inside include a new, high-quality dashboard material and optional new Nevada leather upholstery. Three new real wood trims are available, which adorn even more of the cabin. And for the ultimate custom fit, 16-way adjustable Comfort Seats will be available in the X3.
Optional heated rear seats (part of the Cold Weather Package) are perfect for trips home from the slopes, while the optional heated steering wheel keeps the driver's hands happy."
Typo or do you think the refreshed X3 does indeed have heated rear seats? I'm excited to see where they would put the buttons and if they revised the center console to do so...
