It's not expensive to add AM coverage to the radio itself. However, many cars, especially EVs, flagrantly exceed FCC limits on RF noise pollution, and this is far worse on AM (which picks up noise as signal) than FM (which suppresses some noise and receives less due to the higher frequency). So the cost is not in the radio but in fixing the el cheapo badly filtered car power system so that the AM radio isn't wiped out by it.
Of course after you do all that almost all that's on AM is junk, lots of Rush wannabees, though there is diverse ethnic programming in some cities.
