The Ectomobile, also known as Ecto-1, is one of the most iconic movie cars out there. A heavily modded Cadillac ambulance, the Ectomobile debuted in the 1984 Ghostbusters film, carrying the crew and its ghost-capturing equipment through New York City. Ecto-1 returned on the silver screen for Ghostbusters II in 1989, and it's been a legend ever since.
