what is this a half-wit competition?
come on guyz i think we are talking about off-road vehicles or off-roaders when people say Suzuki "jeep", toyota "jeep" etc.
off-roaders may be 4x4 or AWD and may even be 4x2 (although they should'nt be) ..... their purpose is off-roading so they are called off-roaders ....
Jeep is the name of a car company which is a subsidiary of Diamler Chrysler group) made popular by the images and videos of WW2 .... that it can go places where other vehicles can't or off-roadin'!
its a common global phenomenon in the world that when a pioneering product becomes very popular people name the genre or product type on the name of that brand.....
for e.g. people call diapers=pampers, detergent=surf etc.
