Woodies are a body style, not a brand or year of car. The term “woodie” comes from the type of construction used to build these early station wagons. At the time of their origin, manufacturers didn’t have the capabilities to stamp out steel bodies the size of station wagons. It wasn’t until 1935 that Chevrolet introduced the all-steel-bodied Suburban Carryall, and it was essentially a panel truck with windows and extra seats.
Woodie wagons with varying percentages of wood and steel remained in production through the early fifties. Even though technology existed to build all-metal wagons, the wood bodies were marketed as upscale vehicles for transporting affluent people to their summer estates or resorts. The "station" part of “station wagon” refers to transporting passengers to and from the train station (at the country end of the line).
Wood-bodied wagons required lots of tedious upkeep to preserve the wood. When these wagons reached the end of their gentrified life cycle, surfers picked them up. That led to surf woodies, which remains a popular theme among woodie builders.
As the wood content diminished, many manufacturers maintained the wood look with decals. Even though those cars aren’t technically woodies, they’re still included in this genre because they look like woodies.
Ford led in the production of wooden-bodied wagons (and a few rare Sportsman woodie convertibles). One of the reasons was that Ford owned huge forests just for wood body production. Many non-Ford woodie wagons were custom made by coachbuilders. That trend continues today, with custom-built “phantom” woodies for when all that’s left of an original woodie is the steel cowl.
