In 1998 a Chevrolet Metro could be optioned without a radio or rear defogger, even. New purchase price was about $9k (equivalent to $14.5k today). Somebody was buying those, enough for it to be worth the manufacturer’s effort to produce it.
I suspect a whole segment of people would be willing to consider a no-frills EV at a comparable price point. Hell, if somebody made something new like a base model 90s Civic into a $15k EV without extra luxury nonsense I don’t actually need, I’d be in the dealership tomorrow.
