CMS Buy and sell section in the CMS
 

I would like to see a professional buy and sell section in the CMS (or somewhere in vBulletin software). Today there is not a really good option for this. Using forum threads? Yes it works but it is a very primitive solution for someone who wants to run a professional site.

Example of how it could look like (swedish site): http://www.sweclockers.com/marknad/

By the way, I really like how the CMS looks like on that site.
