When I get my Model 3, it's going to be special to me. It won't become any less special (to me) if there are 10 or 10 million others. Scarcity can come into play when assigning value, but it's certainly not the same thing.
spe·cial
ˈspeSHəl/
adjective
- 1.
better, greater, or otherwise different from what is usual.
If it becomes usual it is by definition no longer special, regardless of how great it is. The car itself will be special though!
