After the second world war the surplus of military jeeps became available to all the people:this was a great opportunity to customized them ! The first "Buggy" type off road vehicles that appeared in Southern California was a shortened Volkswagen frame with a fiberglass body ,oversized  tyres and Vw 1500cc engine:all these customized modifications allowed this buggy running wild easily over the soft dunes of sand along the coast ...because of all these features it was named "Dune buggy".
