I live in a place with very harsh winters, and our used cars usually command a premium, simply because we get cold enough that road salt is no longer effective, so the municipalities generally don't bother in the first place.
I really, really wish my area had that mindset. Even on the -25 and lower days, the trucks will be out salting. Thick enough that it basically creates a layer of grit on top of the snow/ice. I end up undercoating my cars 2-3 times per season, and washing them as frequently as possible (every day sometimes). Every aspect of which is horrible for the environment, but letting the car disintegrate is even worse, so it’s a “lesser of two evils” situation.
