The third remaining time machine was retrofitted with 1950's white-wall tires in Back to the Future Part III, and is now in private hands.
After filming on Back to the Future Part III was completed, this DeLorean time machine was taken out on tour throughout the country of Japan. When it was returned to Universal Studios Hollywood, it was displayed outside as part of the Studio Tour. By 2000, the car was in disarray from the outside elements and stripped of most of its time machine parts. It was briefly put on display at the Petersen Auto Museum in Los Angeles before the studio decided to dispose of the vehicle in 2003, transferring ownership to ScreenUsed — a company specializing in Hollywood memorabilia. ScreenUsed undertook an extensive, professional restoration, which took over seven years to complete. The car appeared on an episode of Hollywood Treasure before being sold in a 2011 Profiles in History auction. It now resides in the collection of a private owner in New England who periodically exhibits the car to share with Back to the Future fans of all ages.
Future Facts
The time machine which was hit by the train at the end of Back to the Future Part III was the "B" main stunt car used throughout the trilogy. To create this effect, the special effects crew cut up the car and frame, rigging it with explosives. The wrecked body panels were reassembled after filming, and the DeLorean was suspended from the ceiling for a number of years at the Planet Hollywood Honolulu restaurant in Hawaii (closed in 2010).
The time machine on outside display at Universal Studios Japan is decorated with props from several of the original time machines used through the trilogy.
The fiberglass hover-converted time machine toured the world and was later on display in The World of Cinemagic: Back to the Future Special Effects Stage show (1991-2001) on the lower lot at Universal Studios Hollywood. Reportedly, it was dismantled when the Back to the Future portions of this show ended in 2001.
Universal Studios commissioned the creation of at least four additional DeLorean time machines to promote the sequels and the opening of Back to the Future...The Ride. These time machines along with other vehicles from Back to the Future Part II were part of Universal Studios' international Back to the Future World Tour in the early '90s.
