If the 300C is to be compared with Lincoln, mid-range Lexus, Infiniti, there will be have to be more of a step-up in the interior than there is from the lower 300 models. Wood trim, headrest speakers, leather covers on the center console & armrests, grab handles, bun coolers, rear cupholders & power jacks, etc.. As for the "dealer experience" add in oil changes for 3/36 or more like 4/48-b2b and a guaranteed equal-or-better Chrysler loaner.
