I think it'* good to join other forums if they support the product/interest that you have. However, many have said that the BC club is like no other... we try to moderate as such to keep discussions on topic and with friendly attitudes.
But what really makes it different is the friendships and family-like comradarie that is spawned by the good-heartedness of the members. So many unbelieveable stories I have witnessed here that are truly remarkable.
You can post pics and questions about your Mustang in the Your Other Rides section.
There are some Ford owners who may be able help you out...general mechanical questions are likely universal... anything more specific and you probably will need to find a ford board.
