Hi guys, again it's me, the always hesitating guy. My daily drive is at bay area. I don't really think I need a sub zero package. For the cold steering wheel, I can covered it with a $30 fake-leather cover. (I won't forget one night in Jan 2011 I parked my Corolla outside overnight and the next day I just couldn't hold the wheel. My left hand and right hand held it in turn every 30 seconds for driving). But do you think I actually need the sub zero package if I want to go skiing during the winter? I spend so much on the car and I want to utilized it (and the unlimited super charge) as much as possible in its life span. I think I can pre-heat the whole cabin with my phone APP 10 min before I enter the car? What do you say according to your experience?
