As far as OEM options I think that roll bar called the "sport bar" is probably the rarest and most desirable/cool for a 4wd. I've only seen one in real life. The pop up sunroof comes up now and then but is rare too. Also some of the original 4WD side grafics/stripes are rare mainly because a lot of these have been painted at this point. The 4wd with automatic trans, pretty rare but not real popular.
