A shape changing car, that may be an alien, is eating people. At first, it seems like an abandoned sports car in the middle of an alley. Two young guys get in it and soon find out it's a horrible mistake. They're devoured. Then, the car gets in an accident and is towed to the city garage, where it starts eating the mechanics, one by one. This is basically a serial killer movie, only the killer is a vehicle. One of the best shape-changing car movies ever made.
