The last forum I participated in had a thread called "What have to done to your car today?" People talked about just what the title implies. Everything from a good wax job to major mods. It was an ongoing thread and, by the time I joined that forum, it was several years old and covered dozens of pages. I see a lot of threads here that could fall under that general heading. I think the Mustang forum should have something like that.
Anyone else?
