In the early 70s, FoMoCo offered a 100,000 mile warranty. We had some really beat cars come in for warranty work, tires gone, brakes squeaking, interiors filthy, only 40K on the odometer. Six months later same car would be back in, another set of tires worn thin, of course the bias ply tires would last maybe 10K, but there would be only 800-900 more miles on it! Had a half dozen of these getting all this free warranty work. Seen this some on the new cars today, but the owner did not know the true milage could be read with a scanner, electronically, and they were about 30K apart. Hmm, makes a person wonder.
