I raised a family and didn't own a van so I don't vote for any of them.

I once had a station wagon (estate car) and was uncomfortable with it for the same reason - luggage. Can you imagine having an accident with 4 or 5 people's unsecured luggage piled behind you with nothing in between? Having my wife's suitcase hit you in the back of the head at 60 or 70 MPH would not be fun. I like something with a separate space for luggage and other heavy stuff.
