You assume incorrectly that people paying for Teslas are buying luxuries "such as sound deadening". They are buying an EV, 0-60 performance, touch screen operations, over the air updates, etc.

"I don't think the new money buying these cars understands or has ever sat in an actual nice car at the same price point."

I'm not sure why you would turn your nose up at people who have different preferences. I guarantee you that there are Tesla buyers who also own other expensive cars at similar price ranges.
