You give up easily.
I made that point on this forum.
The reason I did is because Tesla buyers spend more. Most of the Model S owners had previous vehicles under $60,000... and they were buying $80k sedans.
The same thing is going to happen for Model 3 buyers. Someone who would typically spend 30k on a car will spend 45k because it's a Tesla.
The other reason is simple math.
BMW only sells 70k 3-series each year in the USA, 70k C-Class, 30k A4.... All the other entry level luxury sales are in this area.
There are 400,000 USA reservations for the Model 3. I am going to assume that C-Class, 3series, and A4 sales won't fall to 0 next year.
The Model 3 reservations must be coming from somewhere else, the only logical place are from owners of Civic, Camry, Accord, etc which
sell millions every year.
So it seems reasonable to compare the classes of cars.
