The doors are iconic. Honestly I think they're about the last thing you could drop if you want to invoke "DeLorean". Of course, the steel would not be far behind that, and yet...
Correct — many cars before the DeLorean had gull-wing doors[1], Lamborghini-style scissor doors[2] also predate the DeLorean by many years, and AFAIK, both of these door styles are still available on production vehicles today.
The most interesting thing about the DeLorean is the story behind its creator and creation[3], not any particular aspect of the design of the final production vehicle.
Sure --- but to the average individual, what is iconic about them? People who probably never saw one in real life, maybe only ever saw the one in Back to the Future? What percentage of people even know about those other vehicles?
I think most of what we could say to that would be anecdotal on both sides. So I guess, this is just my anecdotal perspective?
Totally not trying to say that those other things are not interesting, btw.
Interesting they held onto the doors, but binned the clunky former shape and stainless steel.
