New to anything older than 1986..

Picked up a 1966 Dodge Dart 270 from some guy who had it sitting in garage FOREVER. I daily drive it now and it runs better than many modern cars I have owned. I look forward to learning more and more on here! Got it for $1500 in Northern Colorado. Only every owned imported cars. If anyone has any suggestions on what I should do with it please let me know!
