Enter Vehicle Script not working!

Hi, I'm making an FPS game with drivable vehicle. I got my script and modified it. When I press play, my car still active. here is the script

 var Kenderaan : Transform;
 var player : Transform;
 var exitPoint : Transform;
 var doorTriggerLeft : Transform;
 var PlayerCamera : Camera;
 var CarCamera : Camera;
 var isPlayerVisible : boolean;
 var Script : String = "controller";
      
 function Update(){
     if (Input.GetButtonUp("e")&& isPlayerVisible){
         Debug.Log("Driving");
         // make player invisible and still standing
         player.gameObject.SetActiveRecursively(false);
         player.gameObject.active = false;
         // parent player to Exit Point
         player.parent = exitPoint.transform;
         player.transform.localPosition = Vector3(-1.5,0,0);
         // parent PlayerParent to car
         exitPoint.parent = Kenderaan.transform;
         exitPoint.transform.localPosition = Vector3(-0.3,1.5,0.65);
         // Enable Car as controllabe object
         Vehicle = GameObject.Find("Kenderaan").GetComponent("Script");
         Vehicle.enabled = true;
         PlayerCamera.enabled = false;
         CarCamera.enabled = true;
         }
         else
         {
     if (Input.GetKeyUp("r")){
         Debug.Log("Walking");
         // make character visible again
         player.gameObject.SetActiveRecursively(true);
         player.gameObject.active = true;
         // unparent player from everything
         player.transform.parent = null;
         // parent Exit Point to door Trigger
         exitPoint.parent = doorTriggerLeft.transform;
         // disable car as controllable
         Vehicle = GameObject.Find("Kenderaan").GetComponent("Script");
         Vehicle.enabled = false;
         PlayerCamera.enabled = true;
         CarCamera.enabled = false;
  
         }   
     }
 }
  
 function OnTriggerEnter(Player : Collider) {
     isPlayerVisible = true;
     }
  
 function OnTriggerExit(Player : Collider) {
     isPlayerVisible  = false;
     }

just ignore the Malay word... Kenderaan means vehicle.
