When I was driving my Dart home from Iowa I was amazed at how quiet it was. I had no radio and no muffler but at highway speeds it was so quiet. My 2005 Silverado sounds like standing in a wind tunnel compared to the dart. It was rainy and I even used the vent windows to stop the window from fogging. Even with the vent open it was quiet. Vent windows are a marvel of engineering.
