Bid on Ecto-1
The seller notes: In August of 2006 I purchased the original Universal Studios Ecto-1. The car was stripped of all the Ghost busting equipment and sold as an ambulance and with a little negotiation I was able to get all of the roof rack parts and the original light bars. This car was used at the park for over fifteen years for the Ghostbusters Experience, parades and display inside the Florida park. This car is one of three Sony/MGM authorized Ghostbusters 1959 Cadillac Miller Meteor Ecto-1. There are the two original cars used in the films and this one built exclusively for the Universal Studios Theme parks. This car has a rich history and thousands of fans have been photographed with this car. The only major change made to this car was the roof rack. We modified the roof rack to resemble the screen used Sony Ecto-1 original car. Other upgrades are cosmetic and mechanically it's very sound."
We warn the reader in advance that the proof presented here depends on a
clever but highly unmotivated trick.
