AC or No AC

Being in PA, A/C would be nice on a hard top. I know in the charger that interior gets hot (purple car with a white interior, with additional insulation) in the hot humid summers, even when doing 50-60. It really does ruin the driving experience. Given that I want to road trip in an older vehicle, A/C is a must. Traveling alone is one thing, but having a passenger being it the girlfriend or friends it really does make it nice to travel long distances with the windows up, a/c on and be able to hold a conversation due to not having to talk over the wind noise.
