I read that the Camaro Kit was really scaled down, had parts absent from the sprues that were 2n1 extras, etc.
The story sounded too plausible. Sent well before filiming was complete, to film critics and distributors. Remember, it may have been a farce and lightweight comedy, but it was a John Landis/Spielberg film, and both are experts at marketing and product tie ins.
If it is a hoax, it is top notch. Why would a hoaxter put a Camaro kit in the box, and go to the trouble of injection molding sprues with a limited set of parts? Why would they make up a story about how it was NEVER intended for sale (hence no AMT or other logos, and the box was completely designed like.....a promo...for marketing)
If you or I did this prank, wouldn't we make it appear as legit as possible? We would use a picture of a car that was in the box, and we would add details to the box, like scale, AMT, and other stuff.
The Devil is in the details. Only sent to film critics and such, makes it that much more plausible that car modelers and collectors rarely got hold of one. (I assume critics and distributers have a plethora of promotional junk sent to them, and they end up given to their kids or thrown out)
I didnt mean to start a "tastes great vs less filling" war here. I just thought it was cool, and its one of my favorite movies!
"Now WAIT just a ---damn minute! Is that a 1972 Mercedez Benz 500? Thirty eight thousand dollars? TOO ----IN HIGH!" (BOOM!)
"When you consider depreciation, taxes, maintenance, adjusted interest, gas mileage, inflation, not to mention the prestige of owning a Buick Centurion, how can you afford NOT to buy this car?"
