If the moderators decide they want pictures, the classified section should become its own separate entity entirely. I've seen this on other forums. Then with programming, things can be laid out in a form format.

If that's what is going to happen, every sale is going to have to have year, make, miles, photos etc.

Now to the reality of it... The cost and labor that would go into it isn't worth it. I've been on car forums for almost 10 years now and transactions listed without photos have been fine. If you have a question about a particular item, ask the seller for a photo. This isn't rocket science. Most of us who frequent the forum know and trust one another, and if a sale is brought up as not being legitimate, it gets addressed. This is why moderation is important, and if you don't like it I can make you a nice elaborate write up on how to log out of the forum.
