"BEEEEEEP-BEEP-BEEP-BEEEEEEEP!"
The Car is a demonic 1971 Lincoln Continental Mark III modified by the late George Barris that is strongly suggested to be either the Devil or some other demon, with no visible driver (it is also possible that the Devil or some other demon was the driver). The Car existed to destroy and like many horror antagonists was almost completely unstoppable, despite the heroes' best efforts to defeat it.
