apparently that GT500 wasn't the real deal, it's a replica. most movies are like this, even Fast & Furious had fake Nissan Skyline GT-R's
I find this odd. I would expect there to be big money to be made/paid to feature a particular car in a movie, especially movies that are all about cars. Do you mean that it looks like the GT500 but isn't under the hood, or that it looks like the GT500 but won't have any logos on it to define it as such.
