There is a tried and true method for car manufacturers that involves a high end or high performance model that gets people in the door and then they buy a lower priced version. Pick your manufacturer, BMW with their M cars, MB with AMG, Audi with RS, Chevy with their Z cars, Chrysler with the R/T version, etc, etc, etc. Tesla is the same - there will be a range of configurations for Model 3.
So Tesla will sell "quite a few of these cars" but they will mostly be the low and mid level, not top of the line PDLs. That's how it works.
