We have driven the Sienna. We would have boughten a fully load version if a Hybred was avaialbe.
My motive is to have someone fabricate a small bed that would mount into the floor the same way the seats do. My wilfe has limited ability to sit in car seat for a long period, and a bed she could move in and out of would be ideal. We are more than willing to pay 40 to 45K to get what we need in a Hybred.
