I thought I would never own a mini-van; that is until I was pregnant with my 3rd child! I love the convenience of getting kids in and out of their carseats without having to bend over (like in a car), or stand on your tip toes (like a truck). Kids love the DVD player. Great highway mileage, and goes great through the snow.
I can remove the rear split bench seat, and still have room for myself, my 3 kids, and all our bicycles. I also love the on-board air compressor, for filling a low tire, or for topping off the bike tires.
Adjustable lumbar support on front seats would be nice.
