We went to BabyCo at NarreWarren and the ladies there were great, they told us to come back with our car that we're now using and they'd ensure it would fit. I think they brought out a couple of models until we found the best fitting one (and we have a Range Rover - you'd think it'd fit them all!)

You're in Chaddy, the Baby Gallery has also just opened up in Clayton (on princes highway) and at the moment they have some great specials. (including car seats).

For prams, we just got our Phill&teds there for $100 less than at Baby Buntings, which I've found are quite expensive.
