My kids are 6, 8, and 11. We said goodbye to our Toyota Sienna recently and bought a Highlander. The third row is easy to access and overall we love the maneuverability of the car. That said, it’s not as spacious as the Sienna and the trunk space in the Highlander, while adequate with the third row up, is still smaller than our old van. And, while I get that sliding doors aren’t necessarily sexy or cool, it’s so darn easy when you have carpools or drop offs. I do miss that.
But back to your question - check out the Highlander. Have also heard good things about the VW Atlas.
