Have to say that the Corolla I referred to above is spotless wrt rust. Undercarriage too.

This is all the more impressive given that our roads are salted constantly in the winter months here.

The worst I've seen for it are mid-2000s Fords. It's like the frames aren't galvanized at all, but that may be a problem limited to UK models.

That said my (beloved) Nissan Leaf is starting to go orange underneath but thankfully it looks like surface rust rather than rot.

I live in an area that goes crazy with salt at the slightest threat of snow or ice. So any shortcomings in corrosion protection are exposed here.
