I love my Nissan Pathfinder!! Seats 7 , which is great because I have 11 grandchildren, and always end up with at least half of them with me! We also have a Nissan Altima which could seat 3 car seats. but would be pretty tight!!
I have 4 kiddos and we have a Chevy Suburban. Yes it's large lol but we love it. I love that our older two boys can hv a friend over and we can all still go somewhere as a family. It seats 8 comfortably. We also hv a four door dodge 1500 truck. We can only fit 6 in the truck, so we are at full capacity when we drive that. Lol The front seat can be a bench seat. The middle can fold up and down to be either arm rest or room for another person. Now the Suburnan gets about 16-18 mpg in town and around 22-23 on the highway. We will occasionally put E-85 in it when gas prices are high. Hope this helps ;)))
