Audi cars are nice, but ultimately nothing special. Anybody can own an Audi, because the cheaper ones aren't that expensive. That doesn't prevent them from having the R8, though, which at $130,000 is purely a luxury sports car. Everybody who sees an R8 knows that whoever owns it is probably a millionaire. The fact that there are cheaper Audis doesn't minimize the value of the luxury model. The luxury brand essentially becomes "R8," not "Audi."
Other examples: Mercedes and the McLaren SLR, BMW and the i8 supercar. Ford and the Ford GT. So can it be with Tesla and the Tesla Roadster.
