Wooooow! This is crazy! I just signed onto the site, and this is the first thread I stumble across. I actually worked on these cars for Bob back in the very early 90's, like 1991 or 1992. I helped fabricate some of the parts and helped fit the bodywork to the car. As well as work on the GTO with the twin turbo 454 in the back, the drag car with the TR motor up front, and a bright yellow P4 replica. I still have a picture or two of testing them all out at the Enis drag strip before they all went to the Bonneville salt flats. I was told back then that the 308's we were putting the GTO body work on were actually cars that came from a burned up dealership. And we were basically completing all the bodywork, interior work, suspension/brakes, and then putting whatever engine in them that the customer wanted. I only worked there for about six months though, so I never got to see any completed. I can't believe these cars are still in existence after all these years! But to get to you question, I heard many stories there of customers putting deposits down and not seeing anything for it. And even sometimes putting more money into the cars, post deposit, and still not seeing anything. I never knew anyone personally though and have no proof of such. All I can say is good luck!
