Back in 2004, Mr. Chabotte had the opportunity to buy the film car that Griff Tannen and his gang drove/flew around in as they caused havoc in Hill Valley, 2015. Unfortunately, the car wasn't exactly in the best shape at the time of purchase, so Jeff had to begin a complete restoration. The reason for its sad state was because it sat on the studio lot for some time and was pretty much forgotten about. Fortunately, Jeff didn't mind and fully took on the project and was committed to restoring the car to its original onscreen condition. Parts were obviously hard to come by (not to mention the required materials for the hover conversion), so he had to reproduce many from scratch.
