We have the SnS Royale Comvertible for the new bub (was used for DD too), and a Maxi Rider for DD (2.5 years).

When I found out I was pregnant I walked into the store asking for a car seat for my 2.5 year old that had an anchor point and a 5-pt harness, and the Maxi Rider was the only one on the market. I REFUSE to put my child in anything less. I got a lecture on cost from my SIL, but can you really out a price on your child's life? I will buy another Maxi Rider when bub #2 is too big for the Royale, as I am intending on keeping DD in hers until she's 6 or 7 (whenever she grows out of it).

I drive a Commodore and have DD behind the driver and the capsule behind the passenger. If we take DH's car somewhere (Landcruiser), they are put in the same places.
