Wintertime and the convertible

The DS berline was hard to get – and keep- warm during cold weather.

The convertible is absolutely impossible to heat up during cold weather.

So- the choice will eventually come up: Do we add a second heater or not?

Since the car already has an LPG installation and an airco installation under the hood, it is impossible to install a heater to the right….

Maybe a double heater to the left??  This also seems hard to perform.
