Every time I read someone say "the interior of the Model S isn't as luxurious as <insert German car manufacturer>," the comparison that comes to my mind is the Cadillac Catera. Wasn't that car a Cavalier that they put in a luxury interior? If that's the gripe, why not buy an S70 and use the rest of the money to upgrade the interior? Sound? Seats? Which luxury is your poison? With all this noise regarding the interior, you'd think someone would try to solve that "problem" and get rich from it. Are there any modern day coachbuilders working with a Model S? Or are they all trying to avoid Saleen's fate?
