I have my kid's car seat in the rear passenger side. I would rather fit one more adult comfortably, maybe 2 small ones, than have the car seat taking up all that space in the back. Technically you could do it the way you propose, but it would only be comfortable to small people. I think shoulder and elbow room is the real concern more than hip room, of which there is probably plenty. Ultimately, if you want a kid hauler, this aint your car. I should note that I got mine specifically so that I could hall my kid around. Used to have a 2 seater, so I think the thing is a Suburban in comparison. Kind of depends on your expectations. Get a an X3.
