I there a way to know best and worst case scenarios based on a good history and number of bars without Leaf Spy data?
Specifically, I found a '14 SL, original owner, mild climate, daily commuter, with 40,000 miles, but under 10 QCs and still with 12, I believe legitimate, bars. The guess-o-meter says 87 miles on full charge. I trust the seller. The car has a perfect record and was just given a clean bill of health, but of course with limited hard data, by Nissan today. It's 6 hours from me so I can't Leaf Spy it.
Given the miles, assuming no hanky panky with resetting the computer, is it possible to extrapolate best and worst case SoH, AHr and Hx from the history?
