I would like to know if you have try Classified section, which one you use to add-on ? PhotoPost is good? The reason I ask because it is hard to find right add-on classified and other outdated classifieds.
Do you need an addon? We have run classified forums on AVForums with vBulletin for years. We have a few minor addons to change the name of the new thread button to create an advert, but fundamentally, we use the forum system.
