If your car is parked outside, the engine is dead cold and the outside temp is below 20 degrees, do you guys start the engine and let it run before moving the car. I usually keep it running till it reaches the first quarter after the 40 mark.

Is this good practice or should i just start moving it?

Any suggestions on this would be great.

I don't have M-B's answer but I'll tell you what I do: fire her up, check the gauges & warning lights, set her up and drive off, no messing.
Unless it's a plane or a racing car, in which case everything has to be within limits, you don't take off at full throttle. You shouldn't place heavy loads on an engine til it's at normal operating temperature.

Plus I think you'll find the cat lasts longer if you don't leave it idling on warmup.

My 2 cents worth [:)]

Well, I warm up because it will run better. If you start the car with out warm up, it bad for the engine and it may not run better and will give bad smoke back of the car.
