68' Dart

It takes all kinds...those poor things left the factory nearly broken from what I remember reading about them...but so were many pieces of GM iron from the last 70s-early 80s. I bet it would be a fun car with a newer drivetrain...like a single turbo'd LS engine...cheap and plentiful, add about 5-8psi, and you're probably looking at over 400rwhp with a stock idle, and capable of 18-20+mpg with an OD transmission.
