I have a 2014 MS85. I've driven various newer Model S's and have noticed subtle changes here and there and I'm curious if there's anything I can retrofit into my older MS. Maybe we need a list that shows part number changes. A few things I'm curious if I can replace Charger door (newer ones close by themselves and sound much more quiet when magnet/lock turns on to keep it shut). Door sills (newer ones have brushed stainless plate with Tesla written on them) Trunk sill (newer cars have chrome) Instrument screen (newer cars have higher resolution screens) Steering wheel (newer cars seem to have more firm button scrolling/pressing compared to older wheels) Rear view camera (newer cars have better image quality) Brake booster (I am unsure about this as newer cars have "electronic" brakes compared to older hydraulic brakes) There may be more that I'm missing. Feel free to add to my list as I'm sure I'm missing more items.
