It was a cartoon show about a boy and girl car. I barely remember it so vaguely, but I remember the name of the show at least. The cars talked by showing what they were saying on their windsheilds. I'm showing my age with this one. Its from like the late 70's or maybe very early 80's? Its like a tiny fragment of memory residue left in my mind left from very early 5-12 years of age, not much unlike Googlie Eyed Peanut Butter, HR Puff & Stuff and The Gumball Rally.
