I am pretty much decided to get a 2021 or newer S long range. I may buy used, because it looks like I can save $10,000-$20,000. I regularly make about a 225 mile day trip. As I understand it, that is less than 80% of the normal range, and I gather one should not normally charge over 80%. Still, on longer trips, I would want to max out the charge. Is there any rule of thumb as to how often one can max charge?
