is an x3 any wider in the back than a touring e91?

[davidd]

My touring is great, the only thing that stops itbeing perfext is the fact that withtwo child seats in the back there is no room for anyone else.

I know we could get a 5 but they are a lot bigger in every way and we don't need the extra room much. I wondered if an x3 was slightly bigger..

thoughts?
