I know I do not own a Tesla but I have been following the company long enough to at least have an opinion. Asides battery sizes, there have not been too many major changes with the options selection. I understand Tesla most likely removed some options because they weren't making a big enough profit, there was low interest or it was a hassle to manufacture. The two option I miss the most for the Model S is the dark green colour and the option for the rear seats. I think one of the best colours Tesla made was that dark, forrest, metallic looking green. I have only seen one Model S in person with that colour and I fell in love with it! I think Tesla should bring back a green colour... After all, they are a green company. The second thing I miss is the option for what seating arrangement you wanted/needed for the second row. If I recall correctly, Tesla offered an option where your Model S could have 4 seats. By the look of it, it was like the "next generation leather seats" but in the second row. It also included a folding down arm rest with cup holders... I think. My memory is a little hazy because they discontinued this option roughly over a year ago.
