To be a car enthusiast in the Midwest is to live in perpetual fear of oxidation. When local Craigslist posts indicate “No Rust,” it usually means there’s corrosion the owner doesn’t know about or hopes you won’t notice.

I even pointed out “some rust” on the rear shock towers of my first car, a Grand Prix GTP. It nevertheless sold within hours of posting.
