Woodies came from the beginning of the auto era when train station depot hacks were used to cart luggage around from the station to people’s hotels. Later on the hack was enlarged and made into a useful carrier for commerce. Groceries, farms, produce vendors used them to carry their wares. At one point, the hack became fully enclosed and a proper station wagon complete with windows, doors, glass. At that point, the station wagon went from basic transporter to a status symbol.
