Sadly, I know the story behind that fake Ecto at the Volo Museum. That was a fully and correctly restored 1959 Eureka combo that had been owned by a PCS member in Illinois. He sold it when he came across his dream pro car, which he still happily owns, and the 59 started changing hands. When I first saw it at Volo, it was still a correct stock pro car...with a $50,000 price tag on it. Since it didn't sell, they had the brilliant idea to turn it into a Ghostbusters car, and now it has a $150,000 price tag on it. Makes sense, huh?
When I first saw it as a fake Ecto, which was at the Chicago Auto Show, I immediately was thinking "oh no, I hope they didn't do what I think they did". I asked a person who was manning the display about it, and was told that they wouldn't have done such a thing, they are a museum that beleives in preserving cars. Later, when I saw the car again without ropes around it, and was able to get up real close and really look it over, sure enough, they did do what I thought they did.
This one incident has made me lose all respect for the Volo Museum. They loudly advertise having the largest collection of movie and television vehicles, but now I find myself wondering how many of them are also fakes. Additionally, the museum has some sort of relationship with George Barris, who pays an annual visit to the place, and Barris has scrawled his signature across the hood of every movie and television car in the place, including ones that he had nothing to do with!
An hour or so west of Volo, in Rockford, Illinois, is another car museum that also claims to have a Ghostbusters car "that was actually used in the movie". It is a 59 Superior.
