A huge amount of the “value” is in the battery pack. Until the lifetime is better understood, plus any recyclability value, the numbers remain unknown.
“The battery pack itself is the majority of the cost with variations ranging from around $1,000 to $6,000, although most batteries for common models tend to be under $3,000. Along with the battery itself, you’ll need to pay a certified mechanic to install the high-voltage battery. The job often takes a few hours, and sometimes more than a full day.”
