I know this thread is two and a half years old, but I can answer this. It was a 1st gen, a 66. It was driven by the characters Skank and Gutterboy. Sorry, but I've seen this movie so many times I can almost quote it from memory. I have always wanted one of the Chrysler M4S concept cars that they used as the Wraith car. Supposedly, somebody found one of the cars the movie people built off the actual concept car and is supposed to start selling kits from it. That was many years ago, though, so I don't think anything came of it.
