Gearhead Wiki is a place for everything automotive. Think Wikipedia but for cars. Wikipedia doesn't allow a lot of information that would be useful to a gearhead like repair manuals, modification info, car celebrities that don't meet Wikipedia's guidelines, etc.
Jump in, be bold. See something you can improve? Just hit edit and do it. This is a place to dump your gearhead knowledge. The only rule about content is that it has to be gearhead related. That's it!
