My mother has an old car and freezes quickly. So she got this cushion for Christmas and since in their Corsa B Happy. ... Works well, looks just not so ideal from, or slip and happy because your model already has side air bags, the mounting bracket on the left side also omitted. better safe than sorry.
The important thing is: remove when getting out of the 12V socket, otherwise there is ne nasty surprise when you come back, because the car battery is then empty!
