I have made this comments at 1981 De Lorean DMC 12 in Back to the Future, Movie, 1985, 1981 De Lorean DMC 12 in Back to the Future Part II, Movie, 1989 and 1981 De Lorean DMC 12 in Back to the Future Part III, Movie, 1990

No, they just destroyed a mock-up, not an actual car. And these were several cars used, like in most of the movies

I am not sure which DMC-12 was restored

As we know that the DMC-12 was destroyed in Back to the Future Part III, Movie, 1990

You should post it on the movie page

Here is the character car, the DeLorean time machine has been restored to the former glory at Back to the Future DeLorean restoration is complete.
