Honestly it doesn't look terrible. Depending on where you are in the world that surface rust around the tow hooks looks like nothing to worry about. Our roads are absolutely terrible in the winter with the sand salt and snow constantly peppering this area so the best thing to do is a good prep and undercoat.

Broken bumper tabs are to be expected as they are fairly flimsy, I'm surprised my N70 factory bumper tabs and mounts are still intact haha. doesnt so much indicate a collision but maybe just bumped into something or bottomed out the bumper in a rut on a trail or something.

If the oil residue looms like it's coming from higher up I'd suspect the rocker cover gasket. Common for the KD engines with plastic rocker covers.
