I have good tint so maybe that makes it OK. I just direct the front vents towards the back with as few obstructions as possible and there are no complaints. The D4 air con is so good it cools the entire car OK for me. It will be warmer than the front but there are also middle seat vents and there is enough cooling in my experience. We have even done the 800km trip from Perth to Esperance non stop in summer with 7 adults and everyone was happy.
No child seat anchors though. There are three in the middle row. I have put my 90 year old father in the rear row and my wife who is close to 60 regularly rides there so that the oldies can have an easier to access seat. Never any complaints and all quite comfortable. As long as they can climb in (which is pretty easy with the way the seats fold forward to provide access) put the in laws in the rear and the kids in the middle row with one seat available to fold forward for access to the rear.
