We hear about a significant number of modern vehicles going 300,000 or even 500,000 miles on the original and untouched power train these days. We also hear about the "good old days". My own experience in the old days wasn't that great: 1) My 1960 Dodge Dart Seneca 318 V8 3 speed push button automatic, was having transmission troubles by 85,000 miles and 7 years. 2) My 1965 Comet 289 V8 3 MT was a basket case by 80,000 miles and 10 years. It had already had a valve job (burned valve), was burning lots of oil (smoking on deceleration), and had rust bubbles over the up and down headlights. 3) But my 1963 Chevy II 194 I6 3 MT was still running strong at about 80,000 miles and 15 years, but had some rust problems (hole in passenger's floor boards, and perforation of the rear bottom corners of the front fenders). So I'd be interested in anyone who has personally put high miles on an earlier vehicle, lets say model year 1970 or earlier.
