Minivans get much better gas mileage, generally seat more people (and carseats) and are so much easier to get in and out of, especially in tight parking spaces.
I drive a minivan, and my husband drives an SUV. We are both happy. I drove the SUV for a few weeks this summer. I spent so much more money filling up the gas tank! Also, there are some parking lots that have really tight spaces. I did not enjoy having to open the doors to get the kids out. So much nicer having the sliding doors rather than doors that swing out.
We have a Pontiac Montana, and I really like it!
