In 1949, Plymouth introduced the first all-steel body station wagon, the Suburban.  This 1953 could have the new Hydrive automatic transmission, a manual with a torque converter that eliminated shifting between second and third, sharing its oil with the engine.  Specifications for this car here.  Seems like a very rare car because I couldn’t find another on the web.  (The car, a Cisitalia Abarth, at top left sold at auction in Austin for $4.2 million.)
