For buying, selling, researching, restoring, or any other reason you would need info on a particular car, mod, scooter, or what have you. Contact the following people in this list, or for being included in the list please leave a message in the original post. Bait is cool, hopefully kinja will include a messaging feature in the future that will make this much more relevant. Alot of us are on Oppositetalk on facebook too for direct contact (friend requests to me are welcome from all OPPOs). As always with OPPO, these people are doing you a favor by sharing their knowledge that you might not find anywhere else. Don't be a dick.

Also on another note I am proud to be a part of a community like OPPO with such a diverse knowledge base. Thanks to all who contributed and want to contribute! This is a rough draft, but it will continue to evolve from here. Any suggestions on segmentation/layout are welcome! I will continue to curate this as people continue to tell me their strengths.
