Ok...I'll be that guy.
It simply comes down to availability in some cases. We had a choice of 8 used QX at our dealer when we purchased. One of the 8 was 4x4. It had the rear bench seat that my wife didn't like and didn't have the technology package.
We briefly looked at the new ones. They had about 15 on the lot. 1 was 4x4 and it was fully loaded and something like $82k sticker.
I've driven our QX in torrential rain, through moderately flooded roads, and over dirt roads in the time we've owned it. It didn't ever hesitate to get us where we needed to go. Laugh if you will, but it doesn't snow here and the rare days it ices, the city closes. I'm from the North, so it's just hilarious to me, but I'm getting used to it. I had to pick up my son from school early one day last year because of threat of icing. Really?
Anyway, I would have preferred a 4x4, but given where we operate the QX 99.9% of the time, I really don't miss it.
