The Jeep began in the Second World War as a military vehicle for the US armed forces and achieved cult status through its apparent indestructability. Produced by Willys-Overland and Ford from 1941, the 4WD off roader created a new vehicle class that is the grandfather of todays SUVs. The Jeep has moved with the times, but the model made by Fiat-Chrysler still bears the famous slotted front grille.
