Pretty sure those arent leather anything but vinyl and not worth much other than not being torn up... Interior looks clean body looks rough. Seems to be a good amount of rust in the wheel wells, under the doors and who only knows what the underside looks like...
If its not too bad its a nice deal, if there rust all over it Id be scared of it. Maybe part it out and try and get your $50 back (interior, taillights and stuff).
