We also bought a VW Beetle, used, well used, in 1964. It had the split rear window and not a whole lot else.
Heat, you want heat in the winter? Forget it, all it did was freeze up the windshield. The passenger had a full time job of scraping the windshield,,, inside.
In the summer the windshield wiper ran, some of the time, making for some interesting moments.
We drove that thing many, many miles and had a blast doing it. One time my husband got it up to 80 miles/ hr, going down a very long curvy hill in W. Va, he was thrilled,
I was terrified the tires would come off !
We drove it till it literally fell apart, and immediately bought another VW Bug. Oh, to be young again.
