For most of the song, you are led to believe that "Marie" in the song is the singer's girlfriend, forced apart from him by her mother. It turns out it's his six-year-old daughter, separated from him by a divorce or separation.
99% of the song is Meatloaf bragging about how he had sex with a girl in a car. You don't find out until the very end that the whole thing is a lament, and he can't stand the girl, whom he had ended up marrying. "I'm praying for the end of time, so I can end my time with you!"
It's that classic tale. Boy is supposed to meet his sweetheart, ends up waiting for her in the rain, wondering why she's stood him up. Then he realizes he's been waiting in the wrong place all along.
Guy offers to hire a girl as his driver, to show off how successful he is. Turns out, he doesn't even own a car. Yet.
