WE actually own 2 minivans, and all of the kids are out of the house. We didn't even own one when we had kids. Turns out that the minivan is a great car for traveling. Carries a lot, rides nice, handles better than you might think, and has plenty of room for moving around and stretching out while traveling.
Since we frequently travel with our pets, they are also great for the crates that our dogs travel in for safety.
Also being a bit older, they are easier to get into and out of.
I have a Ford Taurus for everyday running and gas saver, two Ford Bronco's, one Ford F150, a boat and if we are considering boats I guess I should add two tractors, a front end loader and a back hoe. Hubby also has a big ass company truck but other then being a GMC I could't tell ya what it was. His company supplied it...big and ugly lol
