What is the best way to send the link's ID to an AngularJS controller?

Question

What is the best way to send the link's ID to an AngularJS controller?

I have a scenario similar to the following:

<a href="#" title="Post 1" id="car1"> Audi car 
</a>

<a href="#" title="Post 1" id="car2"> BMW car 
</a>

How can I pass the ID to the controller? I attempted the following:

<a href="#" title="Post 1" id="car1" onclick="getCarID(this.id)" > Audi car </a>

This method works outside of the Angular controller, but I would like it to be inside the controller. It seems that using ng-click is necessary, however, this.id will not function. How can this be resolved? In my controller and getCarID function, I have implemented it as follows:

angular.module('myModule')
.controller('carController', function($scope) {

    $scope.getCarID = function(elementID) {  
        var car = document.getElementById(elementID);
        console.log(elementID + " has been clicked");
    }
)}

If anything is unclear or requires further explanation, please leave a comment and I will update the question accordingly.

Thank you for your assistance.

Why not utilize the id of the target event?

<a href="#" title="Post 1" id="car1" ng-click="getCarID($event)">

Here is how you can handle it in your controller:

$scope.getCarID = function(event) {
   var id = event.target.id;
}

function Ctrl($scope) {

    $scope.action = function(event) {
        console.log('clicked id is: ' + event.target.id);
    };
}

<html ng-app>
   <head>
      <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
   </head>
   <body>
      <div ng-controller="Ctrl">
         <a id="123" ng-click="action($event)">click</a>
      </div>
   </body>
