Nobody bothered to ask which city you're moving to. Big city, small town, 2 mile commute, 60 miles on the interstate. Small towns don't use tons of salt. So if you live in a small town and commute to a rural factory, its different than Indianapolis.
I lived in the middle of nowhere and we had no salt damage, but rocks and sand would sandblast the underside and paint of our cars. Our oldest truck had holes in the floor from decades of rock. Every car had mudflats not for mud, but to limit damage from dry sand and rock.
If you don't drive it in the winter, make sure you put it up on blocks, never modify it, never take it on a trail, never take it on large rocks, never take it into a forested area, never risk an accident, never take it out of the garage again. Otherwise it will lose its investment value.
I can't believe the damage some people do to theirs on the rock trails in CA. They drill holes in the side of them on purpose just to install guards on the sides to minimize scratches and dents. They have pinstriped paint and spend thousands just to get places to break components.
Salt is a problem if you don't do basic maintenance and pay close attention with inspections each year. You know the issue so address it or sell it now.
