2007 Mercedes-Benz S-Class S550 4dr Sedan (5.5L 8cyl 7A)
I have the limited edition and have never owned or driven a nicer car. It's fast, smooth, roomy front and back and gets surprisingly good gas mileage (25.5mpg on the interstate and 21.6 overall for the first 3000 miles). My wife and my mother rave about the seat massage. I love this car!
I use the back-up camera all the time. The infra-red night vision is useful on country roads. The dual sunroofs provide plenty of light. The "Tucker" turning headlights improve night vision considerably.
My only small quibble is that the infra- red does not turn with the steering like the headlights do but that is inconsequential to the overall driving experience.
