What's your favorite SUV that's great on gas, and can fit 3 carseats? My son has a graco forever so its pretty wide. The baby will have a baby trend carrier for now, then possibly a graco forever. My step son just has a basic high back front face, so not near as wide.

My Kia Rio won't fit all the seats and my fiances Malibu won't either.
