I was just going to day it's not always the car size that helps - it has to be the back seat that's big enough for seats. We have (or had up until 2 weeks ago) a Suburu Forerster and even though it's a decent size car the backseat is quite deceiving - we could fit our 2 seats in (a S & S premier and Unity capsual) but both our seats were right up to the dash.

We have sold the car and are buying a Holden commodore wagon - only for the room! We figure we can have the wagon for next 5-6 years while kids are in seats and we have prams etc then get something a bit cooler/nicer when we don't have to worry about the seats.

My friend has 3 seats in her BMW (very small) and they are all slimline but no idea of brand. To me though it would be just too squishy and annoying trying to get them all in as well as all the stuff you have with kids!
