In answer to the question about where we live, it is a very small village at 3000 ft up a 6 km small and steep mountain road. The road is cleared regularly so it is not a problem unless you want to leave or are coming back from somewhere when it is snowing. I suppose we would put chains on then. But we do go skiing and you can get caught in bad weather then. However as I said before we obviously WILL have snow tyres as we do now on the xtrail. Thanks for all your answers and I think we will go for an NX.
