There are a TON of AMC links so I will try to keep them in as good of order as I can.  Please feel free to submit them to me for adding.

Email lists and Forums

AMC Forum - http://www.amcforum.net   A great site for asking questions and getting opinions on anything from  other AMC owners.

AMC Eagles Nest - http://www.amceaglenest.com   If you own an Eagle, this is the group you need to join.  These guys are the experts when it comes to Eagles!

AMXfiles - http://www.amxfiles.com  A great email list for asking AMC questions and getting answers.  There is occasional bickering on the list, but, if you can ignore that, it's a great email list!

AMCWC - http://www.amcwc.com  American Motors World Club homepage.  A good site for finding a steal in the classifieds section.  Just gotta get to it at the right time.  Got my rust free $2300 Javelin on there.  Called the guy 15 mins after he put it up.  They also have a message board that it seems noone likes to answer.

Southern Rides - http://www.southernrides.com   Even though this is not AMC related it is a great magazine for local Memphis area auto related events.  Pick up a copy if you get a chance!
