Speaking of prototypes, I have this "Muscle Cars" magazine (vol. 5 No. 3) in which there is an article about a true GNX prototype. There are few pictures showing parts that I've never seen and that never came out on production GNX's especially a cast aluminium "ribbed" up pipe and also a flat, aluminium plate differential cover with no "GNX" lettering on it, but there's no mention of any number on the dash. Could this be GNX #000?...I don't know, but one thing I know for sure is that car is definitely a pre-production car, made before the "real" GNX's were built because in the text, it is written that Buick intends to produce only 500 of them and we all know that they ultimately made 547 of them. I'm trying to post a few pics below, but it's a little difficult to take pictures of magazines, but here they are anyway. Hope you like them!...:wink:
