To memorize, you can think about who is the carmaker, say Fiat, Chevrolet, Ford, VW, Citroen, Renault, etc.
So, what make is your car? Mine is a Chevrolet.
And what model is it? It´s a Corsa.
Hmm, I see, the equivalent to Opel...
Other examples, now from related to Brazil carmakers:
Cobalt is a model of GM make.
Ka is a model of Ford make.
Corolla is a model of Toyota make.
And so on...
