If they can sell a nicely loaded III for ~45k, they wouldn't be able to produce them fast enough.
Besides the Cayenne, what other 80k car has sold as well as the MS? There are literally people who would never buy a Maserati or a Porsche who are buying Model S's. There are now 3 in our building.
The sad thing is HOV lane access in California will be pretty much gone by then.
