Seeing in the Dark
The 2007 Mercedes-Benz S-Class has a radar-guided park-assist option too, as well as a "night view assist." By shining invisible headlight- mounted infrared beams up to 500 ft. ahead of the car, it can display a black-and-white nightscope view on the dashboard. 2007 S550 available this month; $85,400
