My husband and I just purchased a used 2004 MPV with 18k miles on it. We have a 15 month old and are expecting another baby soon. The MPV has lots of space without being too boxy or too large. It's easy to get a toddler in/out of carseats in the 2nd row. It would be nice to have a tad more leg room/space between the front and 2nd row but it's fine for kids. I love the cargo space and the "lay flat" 3 row seat. I also like the steering wheel radio controls and the center console that can be up or down. The handling of the MPV is awesome! Feels like you're driving a luxury car instead of a minivan. It turns smoothly and easily, accelerates beautifully (but I'm a conservative Mommy).
Space, smooth, fun ride, excellent handling on curves, interior design/features.
Darker interior for messy kiddies, more space between front seat and 2nd row (for adult passengers).
