220 miles ($35,000) v. 310 miles ($49,000) is a big difference in range and price. Since you have plenty of time to decide I suggest you head over to abetterrouteplanner.com. The site has been updated to include the two Model 3 battery options. I ran a regular drive from Orlando, Florida to Charleston, South Carolina. BTW Charleston is getting a Supercharger this year. Larger battery allows me to skip a Supercharger and saves me an hour on the trip. Leaning toward the bigger battery at this point.
