I worked at Universal as a "Doc Brown" for ten years. One of the perks was occasionally being able to drive one of the DeLoreans around the park. The transportation department told me that the car I was driving was one of the ones used in the first film. It appeared in one shot - when the rear exhausts shoot smoke into the camera. In fact, one of the distinguishing elements of the Delorean I used to drive was you could clearly see the rig where the smoke came out.The Delorean in these pictures is not the one I used to drive. One of the few things you can clearly see in the pictures is that the exhausts do not have the rig for the smoke.Is it one of the actual picture cars? I don't know for sure, but I can say that when the "Back to the Future" ride was open (it's now "The Simpsons" ride), they had a Delorean parked out front. However, it was a replica built by a fan - Universal had no Deloreans left to put out on display other than the one I would drive, which always had to be kept back stage when not in use.Therefore, my speculation is that the Delorean in the pictures is NOT one of the actual ones from the film. It's the replica that sat rusting in front of the ride for decades.
