There was nothing really special about them.
Unless you look into the pto transfer case and the implement they could use.
They were small, 4wd, light, low geared, easily fixed, and an extremely bad ride. And no they didnt have posi or lsd or bld or anything.
I know I am going to get some bad mouthing from this, but the closest thing to the size and handling as the original jeeps is the samurai.
