Please elaborate on your no heat regimen... I can't survive 5 minutes in the car without heat - especially below about 30 degrees. I tried last year... it sucked. In fact, at one point I was coming back from Indianapolis on a sub-zero day, and I was getting range anxiety. I turned off all the heat and only used the seat heaters and steering wheel heat, and still froze my ass off. Couldn't feel my toes. Sidenote, I had to stop at a Nissan dealership in Merrillville for a couple of hours to add enough range to get to the Country Club Hills Supercharger, and still didn't make it... that was a rough day.
