Ha! The steel bits were starting to rust on the Insight too!
Fasteners, fuel/brake lines (see
Tim's recent Insight drama). I never even got a chance to inspect its spark plugs because the coil pack bolt heads were a corroded mess.
No joke: the last Insight to disappear from this neck of the woods actually had bubbling in the aluminum door skins & rear fenders. Even AL will corrode given enough time and horrendous conditions!
