For sale auto parts free
Why can't you post the sales ad yourself? Craig's list allows you post ads in markets other than your own. Something about this request seems strange to me. How did you obtain these auto parts, are they stripped off of stolen cars?
They most certainly are.
Even if not stolen, if you look around you can find plenty of giveaway cars / vehicles that have no title, or salvage title or are stripped out trash / shells. It makes sense when people trying to resell such shit would want to hide their identity as best as they could.
