I wanted to purchase either Tesla or 5 Series BMW in 2014, I picked a BMW at the end.
I went for a test drive and while in terms of ride quality Tesla is not far behind BMW but in terms of interior comfort and quality BMW is miles ahead, Tesla inside looks and feels like a Toyota or Nissan, I doubt anybody who likes Bimmers or Mercs for their interior quality will go with a Tesla, nevermind Maserati, and if Tesla decides to make interior better - it will certainly raise the price a lot which will make it even less comparible.
I think it's unfair to compare Tesla to Maserati (Ghibli), BMW or Mercs, I think Tesla is not for somebody who otherwise would have purchased Maserati or bimmer, but for those who otherwise would have purchased Toyota or Lexus and saved up a bit and went with Tesla instead.
