Doesn't look too bad, but I think the worst part of sitting in the 3rd row would be lack of forward visibility (i.e. kids getting carsick). If you look at the last photo from the driveteslacanada link, you can see that the 3rd row is staring at the "wall" of second-row seats ahead of them. Wouldn't be quite as bad if you only had 6 people and folded the middle seat of the 2nd row.
Agreed - and it sounds like you'll want to bring that middle seat down anyway for much better airflow. And bonus, poor man's captains chairs in the 2nd row!
