Mustang cabin ventilation

Install Mustang quarter windows that can open to provide better cabin ventilation. This will reduce the need for air conditioning during certain times of the year thus improving fuel economy.

Ford did away with that because of cost.Its very expensive to build a wing vent window. all automakers stopped using them. They are also difficult to install. The a/c doesn't use that much gas now days. You could always put the window down a little. It may be just as noisy as a vent window. I usually turn on the heater with the temp on cold. it brings outside air into the cabin
