That brings back some fun memories.
When I was a teenager, one of my first part-time jobs was as a delivery boy for a local Rexall drug store. We made our deliveries in a bare-bones Dodge Dart, with no factory options.
One summer, I made deliveries on a day where the air temperature was 118 degrees. The only way I endured it was because I was young, thin, and drank cold water between stops.
We joked that the stock Dart had “360 Air Conditioning”: You rolled down 3 windows, and drove at 60 MPH.
