Say you store a vehicle outside all winter, if there was an usually cold week, say -20 degrees Fahrenheit for example, is it possible for the car to be colder than the -20 since it sat weeks prior to the -20 temps?

Yes, if it can radiate more heat than it absorbs, which depends on the properties of the car’s surface. This effect/application is called radiative cooling. It’s more common in buildings than in cars.
