We have a facebook page for the dealership - can there be a function that will publish a newly added car to the facebook page? (It doesn't have to be an automatic function, actually we'd prefer a manual "push the button" type function.)
It's an idea to explore, and probably will work as a plugin for autostand.
Similar to the social plugin, but this one would work in the backend.
A new function that you can select the cars to post in your wall.
But as a sugestion:
You have several plugins for joomla that do this for articles. Have you tested inserting cars into articles, and then post the article in facebook?
While that is a great idea, (for someone like me) the person in charge of adding cars to the website is not as technical minded as I am to be able to do this. They would rather (I would rather them be able to) click a button / select a list of cars and have it publish a list to facebook. (Or, maybe it could just copy the needed text / links to the clipboard, and they could go into facebook and paste. That'd work too...)
