Unfortunately it's not as easy as most people are saying... everybody is claiming that they have no issues but that's because they are talking about front-facing car seats for children 1 year or older. You will only be able to fit a rear-facing car seat in the middle seat (or on the passenger side providing there is never any passenger in the front, or an EXTREMELY short passenger in the front passenger seat that willl enable that seat to be moved forward considerably).
The added problem is that the middle position does not have any UAS connectors (Universal Anchorage System), so you'll have to use the vehicle seat belt on the child seat (which is a little more of a chore than the UAS connectors. This isn't really a problem with the rear-facing seats that come with a detacheable base (you secure the base with the seat belt permanently, and then the actual car seat clicks in and out and is transferable from the car seat base to the stroller).
I had no issues with a rear-facing Graco seat in the middle position, but now unfortunately with two toddlers I have to put them on each side and have lost easy access to the third row as one of the seats is too wide to be placed alongside the other one (someone will have to perform some acrobatics to get back there!)
ANother thing you will notice is that the popular car seats that everyone recommends are BIG (Britax, Peg Perego, Graco, First Years). They're not the narrow ones. That's not to say the narrow ones are not safe, but when you compare a BIG car seat with a smaller, narrow one and look at the comfort and protection offered to your child and weigh that with access to your third row, you'll most likely go with the bigger seat and lose the access to the third row if you need 2 seats. With one child you'll have all your options available!
