My wife rolls a 2014 Sienna and loves it too - I don't blame her it does what we bought it for rather well. Yesterday I was told that her next vehicle will be a LX570 - score! three more years and the stabbing wagon will be toast. best of luck to your conquest for her to pick up a car you want, the struggle is realMy wife drives a 2015 Sienna SE and loves it. I totally get it - it does everything she needs it to, and better than any other vehicle can.
Still, I try to plant the seed of "don't you want a Range Rover...?" Or LX570, or anything else I secretly would want to have in our garage. So far, no dice. Still have a few more months before that lease is up to work in it...
