I drive a 2008 Saturn Outlook SUV, I have 2 children and am expecting a 3rd child in a few months. I have a 4 1/2 year old (32 lbs) sitting FF in a Britax Marathon, and a 21 month old (31 lbs) sitting FF in a Britax Boulevard. Both of my kids love their seats. We have a Chicco Key Fit 22 for the new baby. We are struggling with how to arrange the seats 3 across in our narrow backseat. I realize that we may need to purchase new carseats, but definitely do not want to have to buy a new car. I want to make the best carseat choice possible so we don't have to be replacing carseats again in a few years! Again we really love our Britax seats, so this is a tough decision. We have been looking at the Diono Radian RXT because it goes from birth to booster has a 5 point ff harness up to 80 lbs, and can be a booster. Any thoughts, suggestions, configuration ideas would be helpful! Thanks
