Idling the car to warm it up is the worst thing you can do to your engine. The engine takes a very long time to warm up while idling and most engine wear occurs during cold starts and until it is up to operating temperature. It is highly recommended that the car be driven within 20 seconds of starting in the coldest of temperatures.
Gently driving the car will bring the engine up to temperature much more quickly then idling that is why most owners manuals recommend this.
Not only does cold idling cause the most excessive engine wear condition but the car will produce excessive pollution and waste fuel.

The best way to prewarm a car is to use a 120V AC engine block heater with a timer so it prewarms the engine block for about 2 hours.
