A 1959 Cadillac professional chassis, built by the Miller-Meteor company. The ambulance/hearse combination was the end loader variety. Dr. Ray Stantz (Dan Aykroyd) found the vehicle shortly after he mortgaged his mother's house to buy the Firehouse which became the Ghostbusters base of operation. After being outfitted to carry Proton Packs, T.K.E. Meters and other essential ghoul-trapping devices, Ekto-1 became the long-recognized symbol of this movie franchise.
