1948 was also the last year for their legendary-to-be "woodies"—station wagons with classy wooden bodywork —the
wartime scarcity of steel finally in the past. Far from the pre-minivan
they became, station wagons were a niche vehicle marketed to upscale
households. Their putative purpose was to deliver and pick up their
owners, or their guests, at the railroad station. Hence the name. The
van-style body was to accommodate the outsize pile of baggage required
by the fashionable traveler, or to suggest it.
