Thanks girls. I still have plenty of time to research, but am thinking the s&s hi liner may be the go. Then if DD2 needs a bigger seat we will just do another hi liner. I really like my car.... and the thought of having to get an auto doesnt do it for me (I cant find a people mover in manual). The only other standard size car with extra seats was the toyota avensis...but I imagine I would have the same issues with car seats as it looks fairly compact.

Thanks for the link too Ali...its a great read.
