My first solution with counter didn't pass testes cause time run out.
This solution is passing tests but takes a lot of time too.

I ran 2 million iterations and could not replicate, added a try-except for now as a hotfix until I understand the issue better.

Do you know the steps to reproduce this error?

Traceback (most recent call last):
  File "main.py", line 42, in <module>
    test.assert_equals(make_model_year(car), test_function(car))
  File "main.py", line 37, in test_function
    return {'make': make, 'model': model, 'year': year, 'new': new}
UnboundLocalError: local variable 'model' referenced before assignment

this kata is ok
