Hi all, I've searched far and wide, but have not yet found any answers. I've got a 60D in December, and it serves my purpose for now, but as I live in the city, I'm bound to charging at superchargers time to time and once every couple of weeks when I go home to visit my parents (Where I got a 15-40 NEMA installed by an electrician). The 60D was an excellent entry-point for me, starting off professionally and not wanting to exercise my savings in my daily-use vehicle. I would love to imagine a time when I could trade in my 60D battery for a 100kwh battery pack in the future. Do any of you have an idea about if this could become a reality? Has Musk said anything about this? This assumes of course that the hardware does not change so significantly that I would need to upgrade my entire vehicle. As an aside, I've read a great deal on past MS owners trading in their vehicle for a new one - can anyone discuss this here as far as how much they've gotten back and whether or not that's a worthwhile consideration? Really very much looking forward to feedback from you all - thanks in advance!
