Fun little commercial, with some nice close-up cinematography, making the cars look as close to the real thing as possible.
There's a very strange moment where one boy shouts "Look at the box!" followed by an endless pause. OK, what about it?

These toys were Aurora's imitation of Mattels' hugely successful Hot Wheels. The Aurora cars were adapted from its HO-scale slot cars, the Thunderjet 500s. The bodies of these non-powered racers were identical to those of the slot cars, only with rivets in place of the screws that held the Thunderjets together. The rivets attached the bodies to rather poor imitations of the Hot Wheels chassis. They did not work as well as the Mattel product.

Who still has one of these in the attic somewhere!
