It looks like he's missing the entire upper portion of the doors themselves. It looks like the PO thought he'd try to make his own half doors.
Doors are always expensive regardless of model because they are usually a body panel that needs replacing due to accidents I'd guess. Half doors would be cheaper but some people don't like them. Why I don't know because I love the extra room and they just plain look better. They are also much lighter and easier to remove and move around.
I'm guessing with those doors it gets a little moist when it rains.
