The commercial also evokes the boys' need for autonomy. He cannot wait until he grows up and is able to afford this car (in approximately 20 years). He wants to grow up and make enough money to be able to afford a car as fine as a Porche.
Through this need for autonomy, he also has a need to achieve. This commercial makes is very evident that the Porsche 911 Carrera is a very expensive car, which can only be afforded by very elite, successful people. For this young boy, he knows that when he gets his license in a few years he won't be able to afford his dream car. Instead, he tells the man at the car dealership that he'll be back in about twenty years, insinuating that it will take that long for him to save up enough money to afford a Porsche. The commercial, therefore, evokes the need to achieve success and the need to achieve money.
