Nissan Armada
We bought one over the weekend, and I am looking forward to driving it one of these days (as irony would have it the garage door popped a spring and will no longer open, and now the car is trapped

)
I chose this car, specifically, because of driving in the snow (we live in Utah) and the third row seating. It has a knob that allows you to drive in
2WD, 4WD, AUTO, and other stuff. It is set on "Auto" and will automatically go into 4WD if you slip. It also has
traction control which my husband has on his Nissan Frontier. He has tried to spin out, but the car won't let him.
We have two daughters and an enormous dog which is why we were interested in the larger car. We looked at the Pathfinders, but the Armada was much roomier. My husband is 6' 0" tall and about 230 pounds and fits pretty comfortably in the third row (his head brushes the ceiling). With the seat down there is
plenty of room for the dog and luggage.
It is built along the lines of the Titan. It has a
V8 engine so it can move up hills no problem and has plenty of get-up-and-go. As loud as it is when you turn it on, it is an
incredibly quiet ride.
It also has a
back-up camera which is a bonus to help my adjust to the size. I upgraded from a Focus and need to get used to the dimensions; however, when I drive it, it
doesn't feel enormous.
All-in-all, for safety, size, and snow-driving it's worth looking at. Also, it is
Flex Fuel, so it runs on gas or ethanol which can help with the gas-guzzling aspect. Good luck with your search. I hope you find the perfect car for you.
