Just an FYI if you don't already know how to search craigslist nationally. google----> (your search) site:craigslist.org ie; ferrari 360 for sale site:craigslist.org
This can be done for any site out there. i.e.: bling site:ferrarichat.com If you have a few moments to spare, read up on the help section in google searching http://www.google.com/intl/en/help/refinesearch.html or go here for more advanced stuff: http://johnny.ihackstuff.com/ghdb.php
You can also use www.craigshelper.com to run nation wide searches on Craiglist. I think you can't run this site in Internet Explorer. Instead I use Mozilla Firefox browser [by the way I like it better than explorer].
