We have a Van. Toyota Sienna. We like it.
Just because its big, doesn't mean we fill it up with junk.
It is more about how you maintain your vehicle.
I know some people with small cars... and there is TONS of junk in it and the kids can hardly fit in it.
What I like about our van is of course capacity. We can fit 7 in it. And yes we do utilize its space.
Then, the other aspect I like about our van is: it is higher up... thus when driving, I can SEE... what is ahead of me, better than vehicles that are smaller/lower. So visibility is good. And our van, has a "beeping" thing that when you are reversing, it aids you in reversing.
I would not get a Honda civic with kids. Too cramped.
I also have a friend, that had, an SUV. Now she has a sedan. And she doesn't like it, because there is LESS room in it, for her 2 kids plus other things she needs to have in the car. She downsized, to lessen gas consumption etc. But she says it is too small. Her's is a Prius.
But not much room or leg room in the back and in the trunk. Versus the SUV she had. Her kids say so, too.
I, have been in an accident with our van. We did not get hurt, fortunately. We got slammed on the side by an SUV.
