first drive in my (new to me) 72 Duster

Nice car, and a great start for you. Take your time and work through each system until the car is just what you want. I too bought a car from a dealer and have had my challenges. Time and a few bucko's will get it just the way you want!
Exactly! I figured that there would be some issues and I was right....I just didn't know what those issues were! The car will go into a shop on Monday. These guys know this stuff a lot better than I do.
