Rory been in the garage since friday, albeit filthy dirty, but atleast warm and dry. I shall be taking the 4x4 to work today, roads aren't clear and they forecast more snow over next 24 hrs so am not taking the risk with him as there are some hills I don't fancy.
I would say, if the roads aren't clear, ur A500 will be fine to leave for a month, the battery shouldn't drain and if the garage is intergral its not going to freeze, cold, but not outside against the raw elements.
