Has anyone in Europe tried to get an engine block heater installed in their 2010 Prius? I have asked my dealer if it would be possible to get one installed in my new Prius, currently on order. He would ask the distributor if that was possible, but my guess is that is not going to lead anywhere. We have 230V AC here, so no 110V. Plus we have different power plugs. I hope someone has done it already, since I would really like to save the extra gas useage on warming up the block.
