I just bought a 2015 Chevy Volt a couple weeks ago ($12k, kbb says $13.5k.. I got a good deal buying private party). Mile range claims 38 miles.. I get closer to 45 (probably because I don't have a lead foot and don't use AC).
Nissan leaf have significant battery degradation issues.
I assume the Chevy volt & bolt will depreciate around same. Chevy Volt = $33k out the door; Chevy Bolt = ~$35k out the door. subtract $7500 for the fed rebate (do you have a state rebate?)... $27,500.
In 4 years you will sell to me for $12-$15k. Meaning you lost $12.5k in 4 years... Meaning you lost $3,125 per year.
I estimate I will lose ~$1-$1.5k a year for the next 4-5 years.
TL:DR. You're battery will be fine. You will lose $3-4k a year in depreciation. Are you okay with this?
