Ian, I too will be sad to see you go as you have contributed greatly to this forum over the last few years.
It's a shame your views about anything other than what you are driving have not been unanimiously greeted by everyone else, but as this is a forum for predominantly for MK5 Golf GTI's this is something you have to expect.
I will freely admit that some of the things you have said recently have got my back up as I have felt them to be unecessary and in some cases down right rude, but I do not see this as a reason to leave, but that is your choice and yours alone.
All the best for the future!
