No. Being at rest means that there is no NET force acting on it. There may and probably are still forces acting on the car, just the sum of the forces acting on the car is zero.

The car is being pulled down to the ground due to gravity, so there is our first force. And there is also a second force the ground is pushing the car due to newtons third law. And if we are strict, depending on our inertial reference (i don't know if its called that way in English) we could say there is an angular acceleration force applied to the car because its spinning with the earth. FACT: Rest is a type of continuous movement, with 0 acceleration, and 0 velocity .
PLEASE, English is not my native language so I'm sorry if i make any mistakes.

At the very least gravity is pulling down and the ground is pushing up. Note the answers that say "only gravity" MUST be wrong - if there is only an unopposed force, the car would be moving. Since it isn't there must be an equal opposing force.
Also there is air pressure pushing in on all sides.

If it remains at rest then there are no forces acting on it. This is Newton's First Law of Motion.

False.
Gravity is pulling it down.
I might even add friction since the earth is moving but the car is staying with it.
Dont discount potential energy since the car is capable of movement.

except gravity and perhaps solar heat gain
