TSLA will win
The problem IMO is that we need a way to value the difference in quality between a BMW and the Model S if this thread is to have any meaning... the challenge is the fact that it's primarily Tesla fans who post here not the target audience suggested by the OP.
Do we want a serious debate about how we close the gap for the mainstream market?
Actually I think that debate is *too* serious already. We have lots of threads spelling the doom of Tesla because of cup holders and things that Elon already said they want to fix/improve, and "beefed up" the group of interior engineers for. Don't forget that your own personal impression was based on a beta prototype with hand-built interior, used for european exhibitions.
