* Condition: A meticulously restored, pristine example would be worth significantly more than a heavily used, rusty one. The show car itself was likely modified extensively, affecting its value.
* Modifications: The Impala in the show had various modifications (some visible, some not) that would impact its value depending on whether those mods are considered desirable or detract from originality.
* Provenance: The actual car(s) used in the filming are extremely valuable due to their association with the show. This is far beyond the value of a comparable, unmodified car. These cars would fetch prices far exceeding any market value for a similar model in perfect condition, likely in the millions of dollars due to their history and collectability.
* Market demand: The demand for a specific type of car (1967 Chevy Impala) fluctuates, affecting its market value.
In short, you can't put a precise dollar figure on the *show car(s)*. A similar, unmodified 1967 Chevy Impala in good condition might range from tens of thousands to hundreds of thousands of dollars depending on its specific features and condition, but the Supernatural car's value is vastly higher due to its history and unique place in pop culture.
