Econ 101: Why I’ll Never Buy A Gas Car Again Will ICE cars be a lot less desirable in 2020 thus making their trade-in value a lot lower? Will there be a glut of used ICE cars that are a lot less desirable than EV's? In that table of large luxury cars, how many of those who bought ICE cars will have difficulty selling them in 2020 if what people really want are EV's? I think a lot of us would obviously say it's dumb today, but is that true? Will someone who buys an ICE today really get stung with a noticeably lower trade-in value in 4 years?
