Hello Cássio,

You first need to map your cars table with a Model in Django
(https://docs.djangoproject.com/en/1.7/topics/db/models/),
then you can construct your query something like this:

Car.objects.order_by('-registered').last()

Check out the documentation on queries here:
https://docs.djangoproject.com/en/1.7/topics/db/queries/

Have a good one,
