used Volt considerations

I'm looking to get a used Volt. I have a 25 mile commute and want to operate on EV mode as much as possible. Does anyone have a list of things to check for on used Gen1 or Gen2 volts? I'm hoping to get one with a battery warranty but may get an older one to save on money. I'm especially concerned on how to check the health of the battery before purchase if that is out of warrant. Thanks!

Edit: Thanks for the suggestions everyone. I've pretty much made up my mind on getting a Volt. I'm currently leaning towards getting a Gen1. I want to be ready to buy in early 2023 to take advantage of the $4,000 tax credit for used EV's and plug in hybrids. I'll make another post after I find my next ride!
