Add a trigger collider to your garage. And also there needs to be a rigidbody attached to your car. In your script define a bool variable. When the car enters the garage set the variable to true and when car leaves set it to false. Now whenever required check the value of this variable.

var isCarInside : bool = false;  // We consider the car is not inside at first

function OnTriggerEnter(Collider col)
{
    if(col.gameObject.name == "Car")
    {
        isCarInside = true;
    }
}

function OnTriggerExit(Collider col)
{
    if(col.gameObject.name == "Car")
    {
        isCarInside = false;
    }
}

function Update()
{
    if(isCarInside)
    {
        // Your car is inside and you can perform the required function here
    }
}

In above script it is assumed that the name of your car game object is “Car”. You can also check it using a tag, if required.
