Update-we have been test driving tons of suvs-Mazda 9, Santa Fe, pilot, explorer. It seems like the only one that will possibly fit four car seats is the vw atlas. The third row in all the other suvs is too tight for car seats, or more accurately, too tight for little legs sticking out from the car seat. I tend to think the minivan is the way to go. Gotta get my husband on board.
