Some people set up google searches for terms like 'Centurion Turbo' so they get emails whenever Google spots those words in any new posting, with CL ads being the most fruitful. I wouldn't be surprised if there are several people around the country who think a 'Trek mixte' would be a nice bike and would be doing a similar search for one, which could turn up anywhere in the country. If you're willing to ship, this broadens your marketing reach way beyond your local CL range.
