“What I remember about riding in Bugs is how frigging cold they were in the Winter.”
A relative was riding in one with a friend in the dead of winter and he asked if it would be warmer with the windows down.
Ours had an auxiliary heater in it-—on the floor of the passenger side.

Mother bought a ‘63 beetle, It had a gasoline heater that defrost iced windows in minutes. Kept my pizza and sub deliveries toasty warm, too. My first job... $1.25/hour, got $3 a night for gas, took most of it home in the tank, and ran the week on it.
