I'm approaching the one-year mark with my '04 Murano SE (AWD, midnight blue, charcoal leather, billet grille), and I still feel like I made the best choice compared to the other vehicles I had been considering. The Murano is the ideal size for me (I'm 6'5", which is problematic in some vehicles, but I'm also referring to cargo and passenger capacity). I think the Murano AWD handles with incredible confidence in the snow and ice while still offering as car-like a ride as it can. The only thing I'd change is the interior quality, especially the doors, for I'm not thrilled by the expanses of cheap-seeming plastic. I traded in my '99 VW Jetta on my Murano, and while VWs are plagued by terrible electrical systems and extremely poor dealer service (IMHO), they've really got high quality interior fit and finish that are worthy of copying. Other vehicles I considered:
BMW X3: terribly harsh ride. I found the interior cramped and really very narrow. Tail light treatment I found rather ugly, thank you, Mr. Bangle.
BMW 325xi: AWD sedan. Well-executed interior, but cramped-feeling. Generally stylish exterior but somewhat dull revised front fascia. And I knew that a new body style was already in the pipeline. Too, limited ground clearance for some of the mountain roads I use in Montana.
Mitsubishi Endeavor LX AWD: I really rather liked the interior quality of this vehicle except for the plastic "brushed aluminum." Handled very well and had roomy passenger space. Ride quality seemed excellent, but exterior styling did not speak to me in good ways, and Mitsubishsi Motor Co. seems to be struggling.
VW Toureg: Gorgeous exterior and interior fit and finish and well-rated for off-road use, but the interior just seemed smaller and of less use to me than that of the Murano. That, and my already bad experiences with VW of America as a company (too long a list to type here) made me look elsewhere. In my experience, VWoA does not stand behind their products.
Acura MDX: I've read what others here have said about the MDX, and I'll just add that while the ride impressed me, the styling felt past its fresh date to me.
