I have a pretty short commute (14 miles roundtrip) and used the 110 V outlet in the attached garage for the first 5 months of ownership. To be honest it is just fine 97 % of the time. But occasionally I drive to a nearby city about 240 miles round trip. I found that if I drive more than usual the day before, it is hard to get up to 100% before I leave the next morning. In cold weather at 80 mph most of the way I need a supercharging stop to make the trip. Also the last trip I made I came home with about 15 miles range remaining. Driving around more than usual the next day I had to pull into the local supercharger to add a few miles. Charging 6X faster should help eliminate these issues, plus I understand 240 V charging is more energy efficient.
A word of advice though - get more than one bid for the electrical work. The first bid I got was literally double the bid I took. ($650 vs $1300) - both from licensed electricians with large companies.
