The mirrors don't automatically fold AFAIK. But, TBH, I haven't looked through the manual yet.
You have to turn the electric mirror switch round to close them, I hoped they would do it when I turned the engine off.
What sort of mileage do you get out of £47?? I've heard the 197 is thirsty compared to the 182, which was also £5 a tank cheaper. I'm not knocking the car though, its lovely.
