Maybe you should wait and see if Tesla ever decides to deliver the Long Range RWD Model Y. On paper the Long Range RWD Model Y could provide up to 20 miles of additional range over the Long Range Dual Motor Model Y. Also, longer term, new battery technology (4680 cells), structural batteries and other enhancements will increase range.
The latest Long Range Model S, at 412 miles est. has the longest EPA range estimate of any current production Tesla vehicle but you already know that.
