I want to upgrade to a new Tesla and I'd like it to be the ultimate road trip car. Here are some obvious things I want to maximize and what that means for my choice: - range S100D. - passenger space Perhaps the X would be better for this? Maybe the 7-seat configuration? - cargo space Argues for the X, as towing a trailer is potentially an excellent option to have. But no roof box. - toughness/versatility Clearly dual motor and 19" wheels. CHAdeMO adapter. Oddball charging adapters? Hitch? Roof rack? - automation EAP and FSD, for what FSD will mean in the future. - comfort Good sound system. Air filtration. Cold weather package. Seats? Quiet tires? Sunroof? And I want to minimize ongoing costs so free supercharging is clearly a good thing, which currently means buying before the end of the year. Agree? Disagree? What else matters? Any third party things of particular interest? XPEL or other paint protection? Glass tinting? Any strong feeling on whether an S or an X is a better choice? An S has better range and can take a roof box as extra storage, while an X can tow something to provide more storage. Would the X P100D be preferable because towing might need greater power?
