"a boy and a car"

Translation: egy fiú és egy autó

[Milimiliki]

Why the translation should be: egy? Using "a" or "az" should be as good as egy.

[Djenthallman]

A/Az means the, not a/an.

Egy is (if I am correct) something nonspecific. A boy could be any boy in the world. The boy, is more precise.
