I am expecting #3 at Christmas and need to get a bigger car to fit me, DH, DD (3yrs), DS (18mths) and new baby. I love the VW Touran but can't figure out how to fit the three kids in the second row of seats as nowhere can I get dimensions for the car seats/boosters that I'll need. Is there anyone out there who's already cracked this and who could tell what seats they have bought? V. grateful for any help!
