It is really going to be a struggle. I have a had forward facing and a newborn capsule in my 3 series before and my wife could not sit in the middle without sitting sideways so u may find that its is possible to put three seats. It also really depends on the car seat too. The more expensive Safe and Sound seats have side impact protection which makes it even bulkier.

X5 should be better but you may find that it is a tight fit too for 3 chairs. I ended up upgrading my E53 X5 to a Q7 for my wife as it has the larger boot space compare to X5. Q7 also have proper size third row seat standard so if I do have a 3rd child, I can have option of putting one child seat at the one of the third row seat. It will give more room in the 2nd row plus I still have half the boot space which I can fit a 2 pram/stroller and groceries etc.

It is really sux that BMW doesn't make a proper size 7 seater.
