title: Laravel relations relation
body: <p>I have an understanding issue with Laravel Eloquent Models and relations.</p>
  
  <p>I have a user table <code>user</code>. These users can add car license plates, which I save in <code>user_plates</code>. I have a database which contains car models and types. The table name is <code>cars</code>. I have the models App\User, App\UserPlates and App\Car. </p>
  
  <p>The user_plates table has the fields <code>id,plate,user_id,car_id</code>. 
  I save the plate, the associated user (in user_id) and the selected car (car_id (id from table cars))</p>
  
  <p>I added <code>plates()</code> with <code>belongTo</code> function to my User Model which already successfully returns all plates associated with that user. But now I want to get the associated car (car_id inside user_plates). How do I achieve this using Eloquent? The car table does not have any connection to the user table, only user_plates has a car_id and a user_id.</p>
  
  <p>I need to achieve this:
  <code>User -&gt; Plates (can be multiple) -&gt; Plate -&gt; Car</code>. I know how to achieve this using simple MySQL Joins but I want to do it right with Eloquent. Thanks for any help!</p>
  
  <p>Laravel: 6.4.0</p>
