Can objects get colder than the ambient temperature around them?

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?

No (unless you cool them). But they can FEEL colder.

Some materials (rocks, metals, water) have a large capacity to absorb heat. And, in the case of metals, transmit it really fast as well. That means if you touch them, they will seep the heat out of your body without noticeable change in their own temperature. They feel “cold”.

Other materials (like most organics, most powders, foams, air) have a lower heat capacity or heat transfer so low (they’re insulating) that it makes no difference. When you touch them, the heat of your hand quickly brings their surface temperature close to your skin temperature. They don’t feel “cold”. Some materials insulate so strongly (say, knitted wool) that so little heat escapes that they feel outright warm.
