I looked at an EX-L at a dealer, and noticed that the 2nd row leather seats have two small plastic "buttons" near the bottom of the seatback. These look like they could get pulled off by kids, torn, etc.
I believe they mark the location of the lower anchors for carseats, in the crease between the seat bottom and the seat back, as the anchors cannot be seen unless the seat cushions are pushed down to expose them.
