In very cold weather just let it idle long enough for the rpm to come down from 1700 to about 1000(25 sec) and drive reasonable (not speeding off) for the first mile or so and your car will suffer no damage and will warm up faster, just not the motor but the differential, transmission, shocks, and etc, than sitting and idling. Idling wast gas and puts out unnecessary emissions.
