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?

In general, no. Other posters have mentioned a few examples where it’s possible, freezing, or objects with high thermal mass subjected to more cooling previously. There are some extreme examples used by engineers and physicists to get items colder than their surroundings – gas expansion in fridges / freezers, peltier effect, and in extreme cases, laser cooling.
