I'm not saying that's not true but in my case, it was the need for an 8 passenger vehicle that was not a minivan. It was either a SUV or a commercial commuter van.
If you want two bench seats in the 21st century your options are basically all SUVs
After that it was only vehicles with hinged doors and 8 passengers so...SUV or commuter van.
edit: also I live in a northern state in the middle of nowhere. 4 wheel drive and high clearance were not insignificant factors for us.
