NO CLASSIC CARS

A car not having a/c will not make it a deal breaker. If that duster would've had a/c I'd be seriously looking into it.
You just contradicted yourself. If you meant what you said, you'd be looking into it.

Windows down, vent windows turned in, floor vents open, no AC needed. My AC cars don't have working AC, and I'm rarely too hot. In fact, I hardly use the floor vents, those suckers flow some serious air.
