I plan to buy an S85D for my 31st Birthday next January and I have a question regarding Model S in cold weather/charging/pre-heating. I currently rent a bedroom in a 5-bedroom house and the garage is reserved for the owner, so I was planning on buying one of those 'car parking tent' things you can prop up in your driveway/wherever. Charging is not the problem as the SuperCharger here in Golden, BC is ridiculously close to where I live, I'm just wondering if not being in a 'sealed' garage will adversely affect the S (seeming as it would be slightly exposed to the elements in a car parking tent). I've read all the post's in this topic, it's just that most of you store your MS in your garage, and I plan to have it 'outside' in my 'tent'.
