I never had anything against heaters, but thought they were superfluous and/or to pass in states requiring a defroster.

Having driven 707 mostly in cool to cold weather, I'd say they're a requirement, ESPECIALLY in the mild climates where we can drive year-round. I can understand someone in the snow states not needing one, since they tend to drive only in warm months. But if we CAN drive in January or November or a chilly April, we do - and the heater makes all the difference in the world.
