Whilst Caroline was driving the Plus 8 I was playing with the Aircon and heating.
The Plus 8 has a much more sophisticated heater box with both heat control and fan speed adjusted electrically. This means that both are fully adjustable across the range.
The radio has been pulled forward from the heater box: this has two big advantages. Firstly you can see the radio, secondly there are additional outlets, I think the box has three or 4 across the front of the heater box in addition to two on each side.
As a heater it is very powerful and the fan is almost silent.
The aircon is very effective at chilling your feet: with the hood up I suspect it would be good at keeping the cabin cool.
BUT it isn't as needed as one would be on the Roadster as the cockpit seems much better insulated from engine heat.
What worries me is that MMC are quite close to having a proper air blend heater/aircon = climate control as found in modern cars! On the +8 there is room, it would require re-locating the wiper motor and a couple of other small items and of course a new heater box unit...
