Haha unfortunately this has been going on for 4 months at least and when I speak to him , he apologises and explains that his starter motor is broken so he can't turn it off . Asked again today , but he'll be back to the same old tomorrow again I'm sure . May have to do a little grumpy council letter , he was on the street outside the flat today for at least 4 hrs following last nights late antics . Not brilliant neighbourly actions eh ? :/
