wagon V sedan size difference?

[HoldenMad]

I was wondering if there is much difference in size between sedans and wagons, if any?

We currently have a VK sedan and a VT sedan, but can't fit 2 baby seats and a baby capsule on the back seat together. My sister in law has a falcon wagon and has no problem fitting 3 baby seats on the back seat.
I would like to continue owning a commodore, but if I can't fit all the kids in, then its time to move on.

Anyone know about sizes in comparrison on any or all models?

I know that from the VN onwards the wagons are based on the LWB version on the platform, I'd assume the VT would be wider in terms of seating than the VB-VS models though
