We have a 2010 Prius and was wondering if anyone had any luck with car seats for a car that size? The back seat is actually a lot bigger than a compact car and has a comparable seat to our Audi A6. I heard the Cybex Anton is one of tge smallest and will give us some room up front. I really need some real help with this please don't tell me to go out and buy new cars because that's not realistic. I need moms who have experienced this first hand! Thanks!
