I definitely reach -20 every single year and 45C on a hot day in an enclosed space with sunshine on it isn't unheard of either. But it's not too much to ask to just create a space for it that's slightly insulated. Making a small space in the garage be within say -10..45 even though outside temps vary -30..30 like they do where I live, is cheap and easy.
