I just spent Christmas in New England, and was shocked to not see any cars more than 10 years old. If you don't live on the beach, your cars don't rust here. I wonder if it's an environmental policy as much as anything else. When I lived in Oregon, we had snow and ice - and 4 wheel drive, with sand. I don't understand the fascination with salt. I also don't really understand states east of the Rockies.
