I have a few orig paint cars and some of the imperfections on them had to be quite noticeable to the dealer and the orig purchaser ie:runs,sags,blotchy areas,missed areas etc and still they were not addressed.I also work at a dealer and i think people were just not as pickey back then (a car was just a car) transportation ,now- a- days people live in thier cars and are more in tune with them, more than one occasion we had customers flipping out if there,s a damm scratch or dent on the car anywhere!! and they want it fixed before they take delivery, although pretty rare as the quality control is better in the plants the transport and the dealers, remember back then most people bought from the big 3 so the cars sold pretty much reguardless if they had faults or not. But today there is so many companies and models to choose from everyone wants to give u the best possible car for your money...so they say
