Hi!
You can use something like:
{% for item in garage.garagecar_set.all %}
Car: {{item.car.name}}
Price: {{item.car.price}}
Quantity: {{item.quantity}}
ID: {{item.car.id}}
<form action="../update_q/{{item.pk}}/" method="post"/>
{{form.q}}
<input type="submit" value="update"/>
</form>
{% endfor %}
and view like
def update_q(request, garagecar_id):
# get garagecar by id here, create form from request, set new value, save()
it to submit forms with ajax, to not reload entire page every time.
P.S.
it looks you are implementing Many-to-Many-Through relation. Django
has support for it out of the box
https://docs.djangoproject.com/en/dev/topics/db/models/#extra-fields-on-many-to-many-relationships
