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?

If the object can evaporate (ie is moist or wet) then it can become colder than the ambient air due to evaporation. This only works if the air is lower than 100% humidity.
This concept is captured by wet bulb and dry bulb temperatures which are sometimes reported.
