My good buddy worked at a Chrysler Dealership back in 1966 and ordered a 66 Coronet 2 dr sd 426 4 speed. It was lost for almost 3 months and when it got to the dealership he refused the car unless he could rip the engine down and check it all over as it had 90 miles on the odometer. The Mopar rep finally agreed to it and nothing was found. They only had a 90 day warranty on the motor at that time.
