Disabling components in the same GameObject

I’m trying to disable components in the same gameobject, but end up getting this error:

"The type or namespace name `Script’ could not be found. Are you missing a using directive or an
assembly reference?
"

Here is my code:

using UnityEngine;
using System.Collections;



public class CarOnlyDriveIfInside : MonoBehaviour {

	private Script CarC;
	private Script CarUC;

		void Start () 
			{
        
				CarC = GameObject.Find("Car").GetComponent<CarController>();
				CarUC = GameObject.Find("Car").GetComponent<CarUserControl>();
		
			}
	
	
	     void Update () {
		
			if (GlobalVariables.driving == 1 && GlobalVariables.hover == 0)
				CarC.enabled = true;
			    CarUC.enabled = true;
	
			
			}
		
     }

CarC and CarUC are two scripts indeed, but their type is not Script. Their type is ‘CarController’ and ‘CarUserControl’.

You should change

private Script CarC;
private Script CarUC;

to

private CarController CarC;
private CarUserControl CarUC;
