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 t$$anonymous$$s 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.

@HarshadK should I attach this script to the car itself or the garage ?!

@HarshadK first, It gives me an error "bool" I Saw it online written Boolean not bool.

Second, Unexpected token : col.

I mistakenly wrote some C# into it. I don't use JS, so sorry for that.

 var isCarInside : boolean = false;
 
 function OnTriggerEnter(col : Collider)
 {
     if(col.gameObject.name == "GTR")
     {
         isCarInside = true;
     }
 }
 
 function OnTriggerExit(col : Collider)
 {
     if(col.gameObject.name == "GTR")
     {
         isCarInside = false;
     }
 }
 
 function Update()
 {
     if(isCarInside)
     {
         Debug.Log("Car is in the garage");
     }
 
 }
