Wife has 08 Lib GT STI and I have had an 08 STI Hatch and 04 sedan.

The hatch will take a lot more than any of the others as Mike 09 said.

As an aside, we put my two year old Nephew in either the MY 10 Lib GT or the 08 Lib when we have him - he gets a lot more leg room and there is a lot more space in my MY10.

If you want bulk space Foz in the go.
