I think of the "big family car" as a temporary thing too. We have a minivan (which I LOVE btw) and it's useful. We are in the season of our lives when it's very useful, with a 4 and a 6 year old. In 10 years, we may downgrade and get a different type of vehicle, but for now this car is really made for our lives.
So if you are a "I drive things for 10+ years" type, get a family car. If you are a "I upgrade every 3 years" type, get whatever you want.
