jdmuniverse and hondamarketplace are pretty good sites to sell things but there are scammers on every site, as far as no one buying anything is usually because 1) they either have no money. 2) they are just not interested in whats being sold.
And I agree on what was said about the same questions being asked almost every week on the honda/acura tech forum, I guess there is no use for the search link.
