Someone on cso just bought the new SanteFe. I know they posted about it in the Car Safety subforum. Off to go look..
edit to add: I think, based on one particular post, it might be the member named Mingie who just bought one. But it sounds like she went with 2nd row captains chairs. Which would be a viable option for Dominic, if the 1 year is staying forward facing, which is the norm in countries like Australia where babies can forward face legally at 9 months, and extended rear facing seats are not easily found.
Dominic - are you considering keeping your 1 year old rear facing? Do you have a seat that can accommodate that? I'm thinking if you go with a 2nd row bench your best bet for 3rd row access is to have a Diono Radian in the 2nd row middle seat, and in that case, the 1 year could rear face for years to come (and later forward face in it because it converts from rear facing to forward facing).
Maybe post back with where you're at regarding rear facing..
