If it takes that long for your car to warm up, your thermostat is stuck open. Even just idleing the car in sub freezing temperatures it should be at full operating temp within 15 minutes, if you drive the car it should get to full operating temp within 5 minutes. And thats a fact, not an opinion.

I let my car warm up until the stock temp gauge starts to register which takes about 2 minutes. I'm at full operating temp within 5 minutes of driving, even in 30 degree weather.
