Murano Driver
I had the same question a few months ago - and test drove both. I bought the Murano. In my case, I found that the Murano had more power and was a better / smoother ride. and I liked the CVT transmission. I only see seniors driving the Venza anyway > so happy I didn't go that...
I'm sure this has been posted before, but incase you haven't seen it, give the gift of glasses to your favorite SP this holiday season . . . ;)
