From https://www.evunite.com/blog/tesla-owner-demographics/ :

> Based on data pulled from 2,650 Tesla owners, the average household income of a Tesla Model X owner is $143,177 per year.

> The average household income of a Tesla Model S owner is $153,313 per year.

> This compares to the United States national medium household income of $78,500.

143k is about the 85th percentile ( https://en.wikipedia.org/wiki/Household_income_in_the_United... )

So, this is at least upper middle class.
