Todays cars with fuel injection & all the computer & electronic parts don't really need to be warmed up like cars of the 60's, 70's & 80's.
My brother ( who don't care anything about cars ) has parked outdoors all his life. He starts the car, and 8 seconds later he's driving away.
My dad, who parks in the garage let the pick up truck run about 30 seconds after starting before driving off.
Mother only lets the car run barely 20 seconds & she's off & running.
My car, you can count 1, 2 and the motor is running. By the time I get the seat belt on, sunglasses on, write down what the odometer reading is, get a cassette shoved in the radio about 60 seconds have passed, then I take off.
Generally I've found if its above 20 degree's out and your car is in perfect running order about a 60 second wait after starting is all you need.
Its just a matter of preferance.
Good Luck
