When I was in grad school, my favorite uncle in Ohio gave me his 1974 Galaxie 500 that he wasn't driving. He kept a bag of road salt in the trunk. It leaked. Ate through part of the floor in the trunk, part of the frame, part of the brake lines. I remember trying to jack it up with a bottle jack to work on the brakes, and the top of the screw punched a hole through the frame! But I got a few years of use out of it.

Salt and cars don't get along!

Cheers,
Scott.
