Lets see, 50-65 year old American cars, located on an island off of the coast of Florida. They have all been in continuous use since new, no direct parts supply network from Detroit. Most probably have 300-400,000+ miles on them, and been MacGyvered' since Kennedy was in office. What could go wrong?
Spent most of my life in Southern California. There is still lots of good 50-65 year old Detroit iron in the Southwest.
