a good friend of mine has 3 under 4 - and they have a Forester! So i know you CAN fit in 3 car seats - I know one of those is a maxirider too, and they arent really narrow.

We are in the same boat at the moment - suggestions we have had -
Forester
Mazda Tribute
Commodore wagon
Falcon
and then all your large 4wds - which we dont want to do!
