To my surprise, yes! I work 12hr rotations as a nurse at my local hospital and have parked free on a lot close by all winter. Not once had my car failed to turn on especially after being outside for more than 12 hours (this was during dec-feb/March). I would prefer to have it plugged in but I'd rather not spend $20/shift to park in the parkade The stock tires were spectacular on snow, very impressed! My car's first experience with winter's extremes were awesome!That is too cold for me.Was it easy to start at those temps?
