Re: Leasing versus sales
It's called choice. You can get great service and choice from a local installer and they will do a great job.
Or you can go to Tesla and get a package of it all, working together with a single app for the car and battery (as for least capable, that is absurd, it may be expensive but it is also capable). Your choice.
As for a supercharger - For exactly what you said , long trips or multi-day excursions. You don't need to do it often to appreciate how good the Tesla supercharger network is. Even just a couple of times a month . Regular charging at home/work is what is great about an EV. Always having a full tank in the morning. But addressing the anxiety about long trips was key to getting take up of Tesla cars when there was limited alternatives around.
