SVK's rusted out pickup is nothing extreme--I'm sure the new owner is pleased to get it. Had a '62 Chevy 3/4 ton, 235 straight six, 4spd, when it was 12--16 yrs old. Talk about a rust bucket--you could hear it rattle coming down the road. it was step-side, and one of the rear fenders fell off and was dragging on the road as my wife returned from work one time. She tied it back in place with baler twine, enough to get home, and I had a neighbor weld angle iron to secure both fenders.
Later, we began to smell gas and wondered why. The mounts holding the cab to the frame had rusted away and the cab sagged, until a bolt or something punctured the gas tank as it settled. (Gas tank behind the seat back then.) Replaced the gas tank, jacked up the cab body, and kept it suspended with some blocks of 2 x 4 between cab and frame. Got a few more years out of it before I rebuilt the engine and transplanted it into a less rusted body & frame.
