Universal Studios: "Hero A" DeLorean from Back to the Future
About the car from 2013 article on Auto Blog website: Fans of the Back to the Future trilogy will be pleased to learn that Dr. Emmett "Doc" Brown's modified 1981 DeLorean DMC-12, better known as a time machine, is on display at Universal Studios Hollywood in California after a painstaking museum-quality restoration over the past year. While Universal used a handful of cars during filming from 1985 to 1990, this particular vehicle is referred to as the "Hero A" car, as it was the only Delorean featured in all three films.
The Time Machine Restoration Team was tasked with bringing the car back to its original state during its first appearance in Back to the Future, complete with its plutonium-powered flux capacitor (later versions were modified to develop power for time travel from lightning and garbage). From what we can tell, the team's work appears flawless.
