Sounds like you've reached a very small audience. Not sure what the temp extremes are in Finland, but I imagine most in the US and Canada keep the Porsches in the garage and not used frequently.

Haven't heard of anyone using an auxillary heater in a Modern car. When i was a kid we had one in our VW bus but, c'mon, that cabin was huge and aircooled motors don't make heat quick enough. The Cayman/Boxster cabin is so small, I'm not sure I'd want more heat.
