Remarkably, it took 25 years from the invention of the car for one to be offered with a fully enclosed interior, that being the Cadillac Model Thirty of 1910. Demand for cars that didn’t force drivers to brave the elements soon became popular not just in the US but also here and in mainland Europe. This was a trend we noted in 1924 as progress was made in overcoming the not insignificant challenges of ventilation, rattle and rigidity. We also predicted that a corollary of this would be the improved design of open and convertible cars.
