As a family person that runs to fruit market every several weeks and brings back a boot load of fruits in boxes it is hard to understand how a sedan can suffice.
Having said that huge SUVs are overkill too, something like Subaru Forester/Outback or RAV-4 seems to be the sweet spot for people with less than 3 children. With 3 children you start looking at something with 3rd row of seats.
