There is a way to put the Volt system in 'Storage Mode', or some such term, to keep the background load off the 12 V battery.
Hopefully the Spark EV has a similar mode. But then when it arrives at the dealership and they power it up and put it on the lot, they probably don't put it back in that mode.
I also read on this forum about someone buying a Spark EV that sat on the dealership lot for 500 days. Is that possible?
As said before, a few days with the 12 V lead acid totally discharge damages the battery irreversibly.
You could suggest a sort of load test by leaving the headlights on with the car not powered up. They could measure the current being used with a clamp-on ammeter and calculate if the battery is meeting its 'Reserve Capacity'.

GM needs Modern Troubleshooting tools for Modern EV's.
3 step Trouble Tree, 1st try, nope, 2nd try / cost $800. 3rd try fixed it.
