This OPML directory is maintained by everyone whose cars are listed. By means of the OPML inclusion feature, I link to each car owner's list just once. Anytime an owner updates a list -- no matter where it's hosted -- the change is reflected in this file.
If you want to make an OPML file listing all the cars you've ever owned, follow the format illustrated in the next node -- with the cars, not your name, as the top level. I'll put in your name on the master outline. After you have made your list, e-mail me at amybellinger AT gmail DOT com, tell me the URL of the OPML file, and I'll include it in the car roll.
