Did you know you may remove pictures and Topics?

  I just ran to adds this week for items that sold (Thanks!) and noticed I can A: remove the photos and B: remove the entire topic. The options come up at the bottom of the screen for you, one is to UN-check the photo after clicking modify and the other is at the very bottom as a choice to "remove topic" you can hit. It will ask you to verify after you do it so your safe.
  Doing this will help the Mod's reduce the data stored needlessly I believe so try it if you sell or don't need a topic anymore.

I knew about the pics feature but not the topics.

The ads get purged on a regular basis. You should only be able to delete a thread with no replies. Since replies aren't allowed in most of the Classifieds sections this should work. It's not really necessary though. Those section make up well less than 1% of the site.
