Forum For Mechanics/Tools
There are several forums for used car parts, but nothing for tools, equipment and related parts. The existing forums have strict rules about what can be posted, leaving all other automotive stuff to be listed in the "USED Miscellaneous Goods ONLY" forum, where they would get lost in the myriad of stuff posted there.
So perhaps a forum for Tools/Equipment or even just a Misc Automotive forum.
Better yet, if there was a Tools/Equipment forum then you could add another category (WTBR) for Wanted To Borrow. I often see posts in VAC or tech forums by people looking for a specific tool/socket (or OBD code reader) they need to work on their vehicle. Much better to have them in one place instead of strewn all over various forums.
