Btw, I didnt vote in your poll because, you put forth a C class interior and asked when tesla would "get to that" and there was no choice in the poll for "never, for that type interior".
FWIW, I dont consider a BMW 3 series as a "luxury" car at least not till you get to "the real M3", nor do I consider a C class a luxury car. Its car by a company that makes luxury cars, but its (to me) not a luxury car, and people on those forums (mercedes and BMW) would also tell you a C class isnt a "luxury" car, nor a 3 Series.
Mercedes luxury starts at E class, and BMW Luxury starts at 5 series (for example), at least to me (and to people who buy those brands, except for those who can only get the entry level one).
Fun fact ( I have shared this before). I have known my BMW service advisor for over a decade, through multiple lease cycles etc. The cars come with free maintenance for 3 years so once a year you take them in for free. Anyway, over lunch one day we chatted, and he told me "you wanna know the PICKIEST customers we get for service here (bmw dealership)? Its not the M3-4-5-6 owners, nor the X5 owners (no X7 existed then). Its the person who buys the 320 and wants to act like we should be kissing their $@%@% because they own a BMW. They complain the most, by far".
I get that this sounds snobbish, and its not intended to be so, just put forth my opinion on the market for this car. Its a very high performance mass market vehicle. There isnt much "luxury" about it, except for the battery and tech. It will likely stay that way for the forseeable future. If you define luxury in this space as the battery and tech, then its a luxury car. If you define it by fancy interior options, etc, it isnt (nor is it actually built to those standards), and it likely wont ever be that.
