ECTO-1 (GB4)

The ECTO-1 from Ghostbusters 4: Hellbent is a 1959 Cadillac Miller-Meteor Ambulance which is a combination of ECTO-1, ECTO-1A, ECTO-1B, as well as extra elements from the ECTO-1 in Afterlife & Frozen Empire. It has a LED signs from Ghostbusters II on each side, and the sirens, satellite dish, and gas tank from it as well, in addition to the GBII bumper being put back on. Everything else is from the original ECTO-1. It has a gunners’ seat, like from Afterlife, which means the ladder is on the left. The Super Slammer Muon Trap is also on there, along with a brand new ECTO-Drone hatch. The logo was changed to the Ghostbusters 4 logo.
Once getting the job, and waiting for a call, Zach suggests to Winston an upgrade to ECTO-1, which was still what it looked like from Afterlife, after that, Winston upgrades it, and the new car looks beautiful.
