It's too difficult getting kids into and out of child seats in the third row, I've never seen anyone put child seats back there, I would guess research bore that out, so they didn't.Thanks for finding out what you can re: child safety. I realize that's a limited area of interest for other readers!
Also curious about Latch (ISOFIX) anchors in the 3rd row. Audi has two sets in current Q7's third row, and we have one set in our exciting Sienna driving machine.
You can see the Latch markers on the 2nd row outboard sets, but not on 3rd row seats. Will all the safety "tech", you would think... ??
