So the frost is upon us, and leaving early in the morning is a pain, whot
with scraping the window and all.  I park in my driveway, so I don't have
the benefit of cover.  Early on I purchased a 110 volt "Ceramic
Heater/Fan", like the one advertised below.

I run an extension out to the car, and I put a timer on it where it plugs
into the house.  Now when I leave in the morning my windows are defrosted
and the interior in toasty warm.
Hopes this helps some of you really cool lot.
