Indeed it was

I actually saw an original Twister Mustang at a car show about 10 years ago, I thought it was some aftermarket package, only to find out it was the real thing that was actually sanctified by Ford.

I think it's a good idea that Ford is doing this for the Mustang. Hopefully over time maybe it'll inspire Dodge to do the same for the Challenger. How about an all-white Vanishing Point edition? Perhaps a red convertible as a "Natural Born Killers" edition (OK, that's a bit of a stretch but you get the idea).
