How can you identify a Dodge Demon?

I'm wondering when we start seeing 2018+ Dodge Demon clones? They don't seem to have the resale value as classics. Yet. Now that their run is ending? I may consider picking one up as a future collector?
I just don't think anyone will ever be pulling any of these new cars outta a barn 50 years from now and them be worth anything. I could be wrong.
