I test drove a fully optioned model xDrive40e at the local dealership.... and made me now question what packages I've order for my X5.
The Driver Assistance Plus ($1700 add-on) was really cool, it would tell me if there were pedestrians, warn me of close vehicles, and even display the local speed limit (which I think it scanned from the signs?)
I also loved the 'surround view' which gave a top-down view of the vehicle and surroundings for parking in tight spaces...
