Change the object the camera looks at?

Hey all, I believe the answer to my question is fairly simple to some of you but because I’m not a programmer by any stretch of the imagination I can’t get it figured out. Here’s the situation:

I’ve got 8 cars lined up with a camera looking towards them:

[Car1] - - - -[Car2] - - - -[Car3] - - - -[Car4]- - - -[Car5]

                  [CAM1]

What I want is to change the car the camera has to look at when I click the left mouse button. So the camera starts with looking at Car1 and when I press the left mouse button it has to look at Car2, and so on.

Does anyone here know how to do this?

Here me out… When you click the left mouse button have the mouse add on to a number somthing like this

var Num: int;

function Update(){

if(Num == 1){

Camera.LookAt("YourCameras");

}else if(Num == 2){

Cmaera.LookAt(YourCamera#2"); 

// and so on...

}
}

function OnMouseUp(){
Num ++;
}
