Range Extender -
$55-US for both @ WalMart.

LOL - I've used that "range extender technology" in my Roadster. The Model S with its extra range and "Range Mode" has so far been able to keep me comfortable without resorting to that!
For my 2nd trip to the city in the S, 180 miles total, I decided to forego cabin/seat heat since it was a mostly sunny day. Indeed there was solar gain thru the windows, but I suspect the glass all around is the 0.32 factor IR-rejecting kind. Enough gain to keep the dog & my upper body warm, but the legs & feet were cool. Not enough to cause shivering but it took the long walk across the WalMart lot & more inside to normalize. So I grabbed the leggings & muklucks to keep in the S at all times.
Roadster: need the leggings as well as heated boots, if such even exist. And the cabin insulation/soundproofing upgrade.
Seriously, NEVER hesitate to use the seat heater! It has NO measurable effect on your range.
