How about a 2.0 TFSi Jetta? Loads of boot space for all the kids paraphernalia and 4 doors, along with all the joy of driving a GTi? I have one and love the huge boot, comes in very very handy. I know the general UK public don't like sedans, but as a family car, you can't go far wrong, plus the added security of being a four door where you can lock the boot out.
