Where do you think classic cars come from? Classic cars are constantly being created as existing cars age into that bracket.

Sure, and people buy them up, just as they buy land. They're a finite resource.

[scatters]

They are an elastic resource. The amount being created is responsive to demand.

Also, they're substitutable; if people can't afford classic cars, they'll buy art, or wine, or yachts, or Rolexes, or a thousand other luxury goods. Land is only imperfectly substitutable, and it substitution has definite economic costs.
