People keep saying "Oh, it should be EASY to replace the cells with new ones, just pop 'em open and..." and then we don't hear about anyone actually doing it. Which means either it's wildly more work than they were expecting, or wildly more expensive once they DO do the work. At this point, I wouldn't buy a BRAND NEW 10 YEAR WARRANTY for $30k, for example, because I can buy a Bolt for that, get 200 miles more range, and a free B2B warranty on a whole new car.
