SURVEY SAYS....YOU ARE BOTH WRONG !
The Swamp Rat
“The Beverly Hillbillies” pickup, affectionately known as “The Swamp Rat,” was a 1921 Oldsmobile Model 43-A roadster with a 43-horsepower, four-cylinder engine. If you bought this then-midlevel sedan directly from the factory, it cost $1,445.
Custom car designer extraordinaire George Barris was tasked with building a vehicle suitable for the Clampetts. He found the ’21 Olds behind a Fontana, Calif., feed store. It was already weathered and lacked a back end, but Barris was fine with that.
