Thanks, you have put my mind at ease. And your suggestions, both of which I will do, make sense. They are obviously from someone who knows all about cold weather starting, given your locale in the great white north of Montreal, Canada!
May I ask, do you use any kind of battery, block, coolant or oil heater in your MB? I am thinking of installing one in mine after this past weekend, but don't know much about the various types or their pro's and cons.
