WOAH WOAH WOAH ... the DeLorean wasn't a failure - it helped making time travel possible :),(reply>), The only thing the cars have going for them are their looks and their movie fame. They were complete crap otherwise...,(reply>), Well they are still selling them so it's not a failure,(reply>), John 117  My biggest question is why they used the bttf time machine toy instead the reguler car toy,(reply>), +The Mad Hammer no? wherent the cars pretty bad?,(reply>), Even if a invention was a failure in one regard and a success in a different regard It may still be valuable to have it in the museum. Part is to learn why something failed. Sometimes there design failures. Sometimes there economic failures.<br><br>As for US emission laws limiting the engines. All other manufactures have to live under the same constraints. It the engineers job to actually solve these issues while working in those constraints. We have far better engineers today under far more constraints then the designers who made the DeLorian had. Of course we have also learned a thing or two about how to make engines since then.
