I think kev sharp sold some spoiler caps for over a ton last year!!! so them spoiler caps look cheap!!
thing is if you have a mint 3dr and your spoiler caps are missing where can you get any??? hence the reason the price is what it is..
supply and demand
I know someone that has just sold a van load of new RS500 parts including several

new front splitters and rear spoilers as well as New header tanks

, he sold them as a job lot cos he didn't want to get stuck with them, he made a mint but could mabe made loads more selling seperatley.
BTW all I know about the new owner of the stash is that he lives in Ireland..
the parts were all found in a storeroom somewhere in the depths of ford in daventry (IIRC)he found out about them as he works for ford.
