Converting to gallons in not something I do often and so it's not easy to do it mentally. There's also three different gallons to choose from, sooo....That gas price is about $6/gal, so you probably could have just wrote that, although your other details are quite informative.
Welcome to the club! 500e is a first-EV for many of us, mostly due to low cost, & projected battery longevity due to its thermal management system.
I chose the 500e cause it seemed to be more fun and closest to what a "normal" car would be. No unnecessary stuff. Also - pretty light.
