New guy, From Kentucky

Welcome to the site

any of the three would probably make a cool car. From your post, I'm guessing you are young since it is your 1st car. Look at it from economics, what is purchase price of each, what will it take to make it dependable, where can you find parts for it.

The Charger doesn't run, so might cost more to get it on the road

the 64 Dart looks good, but as old as it is and many parts not as easy to find.

the 70 Dart, parts from many years work on this car, if it is a running driveable car and looks decent as is would be my choice just for fact so many parts still available for it.

Good luck with your decision
