This is actually a difficult question for me to answer. On one hand, I love my MO, and if I HAVE to have an SUV, this is the one to have.
On the other hand, Nissan service has been treating me like... Well, like most other people on this forum. And that is NOT GOOD. They have pissed me off enough that I really wouldn't want to buy another Nissan.
So, if my MO were to be totalled today (which is entirely possible since Seattle is getting some freakish weather for this area and people here have no idea how to drive <rant> <rant> <rant>) I would have to shop around. I'd look at the FX, the Mazda CX-7, Volvo V70-R (although obviously more expensive), MAYBE do another test drive in the Dodge Magnum.
I believe I like the Murano better than those other vehicles, but I'd have to do some serious thinking to see if it would be better to avoid Nissan service. As for the FX, I'd have to look at the forums of course to see if Infinity service is better than Nissan, but I believe it is (amazing how that is, huh?)
