Cars are not very practical. Small and cramped on the inside, and not great for a family.
Trucks and SUVs make for great family movers.
I have a full sized half ton truck, It is the main family hauler. But I use the bed alot and tow my boat or trailer all the time.
But something small like a Ford Escape is perfect for most, and that is why there are so many of these compact crossovers on the road. They are bigger than a Car, higher up, and the back seats can be fold down to allow for a lot of storage room. Our secondary Vehicle is a Escape titanium, and see these everywhere along with Rav4's and CRVs. Really the only 3 compact crossovers worth looking at IMO.
