My wife has a Model X and we sold her Model S. Currently there are many features standard on the Model X that are missing from the Model S. The price delta is relatively small, but I hate the FWD of the Model X. I have a Model S on order for November delivery and my hope is that many of the missing features will make their way into the Model S before then: 1. Ventilated seats 2. Adjustable shoulder straps for the front seat belts 3. Adjustable headrests 4. Door pockets 5. Automatic door open/close 6. Powered rear seat fold-down Anything else missing? Seems to me that these features should quickly make their way into the Model S since they are priced nearly the same.
