I did read the quote--but if you upgrade from the 85kw to the 90kw battery pack--do you get an entirely new battery pack? Is it is to be in the $3-5,000 range? So the battery degradation % recycles to 100% and another 8 year guarantee? If true, then a car with 10-20,000 miles 1-2 years old, might make it reasonable. Is my Math wrong here?
