I work on my own vehicles as well. I’m looking forward to my first oil change at 100k miles, lol. With gas at $4/gal and paying 14.48¢/kWh, I’m getting 107 mpg equivalent dollar for dollar not even hyper-mileing. As far as long term costs go, I’m expecting to get 250k miles out of my batteries and if the Bolt doesn’t last that long, I’ll repurpose the batteries into a whole home battery backup. Even then, if there’s a battery swap that becomes available to her a faster fast charge, I may turn my bolt’s battery pack into a home battery pack sooner. I’d much rather reuse what I got than recycle
