Last Century, I owned a '92 Diesel, long-bed pick up truck. Never had a problem with it until I had put one hundred, thirty thousand miles on it. I had changed oil belts filters, etc. fairly much on schedule. At sixty thousand I changed the timing belt, only to see that the old one looked identical to the one I replaced it with. I am convinced that the darn truck, would not wear out. Then at one hundred, thirty thousand miles the body started to fall apart. I discovered the severity of the problem one winter day when I drove through a puddle of snowy slush, only to have the floor under my feet erupt in an icy blast up my right leg. The only body panel that was not severely weakened or holed by rust was the tailgate, and it would fall off if left open. I sold the faithful old truck to a fellow who donated it to a missionary church group. I imagine that little truck is still out there somewhere in the third world happily running... without a body.
