My first car with a sunroof was a 1961 VW Beetle. The top was a cloth and vinyl affair, powered by my right arm. It folded up like an accordion as you slid it back, and stuck up in the air high enough to whistle seven different tunes at highway speeds. It was so low tech that unless the top got ripped or torn, there was almost nothing to go wrong with it. And unless you pitched both ends of a doubleheader the day before, there was always power to open and close it.
