private use because of the train damage, so they had to be crushed when Universal Studios no longer needed them. Of the 5 that escaped that fate: 1 stunt car (originally at the universal theme park) was shipped to a theme park in Australia, for World Expo '88, in Brisbane, Queensland, but is now believed to be back in the US. Universal kept one 'hero' and one stunt car for use in the Entertainment Center display – the two originals have since been sold to a private collector in the US; another, a convertible, disappeared for a while before being sold to the former Cars of the Stars Motor Museum in Keswick, Cumbria, England This convertible was sold to the Dezer Collection, Orlando, Florida when Cars of the Stars closed. The fifth car is believed to be in private hands in the UK.

Press releases regularly appear claiming 'original screen-used' cars are being sold. For example: on April 4, 2007, "one of the four KITT cars used in production
