AWD would have been great but they mated it with a CVT transmission which is questionable at best. I was seriously thinking about buying one last year but walked away because of the transmission issues.
Interestingly, Nissan seems to have gotten their CVT to work, unlike Ford/ZF. Most of those Muranos running around have a CVT behind a V6 and AWD - and they put it in their Maxima last year, no problems.
