We test drove the new Grand Carnival two days ago, and really liked it. We just wanted to know what they were like (looking for down the track), and they have a HEAP of room. each seat (except the middle of the third row I think, like Mylitta mentioned) has the anchor point attached to the seat base, so the straps are right out of the way. And whilst the second and third row don't slide forward or back, there is more than enough leg room for tall adults, and a cavernous boot space. They are really wide too.

On a separate note, they go like the clappers. (I swear I didn't mean to scare the salesman!)
