Good God Granny,er Cletis.I suppose if you air up a flat tire,it is not original,cause it doesnt have the original air in one tire. I think you are carrying it a way too far.Now I am one of the older hot rodders on this site,but I still enjoy looking at original type trucks. If what you are saying is factual,there would be very very few original vehicles in existance today. Generators wear out over time paint becomes dull if the truck is used at all,tires wear out,etc. By your description a person would have to buy a new vehicle and keep it sealed in a vacuum bag for 50 years,to have an original vehicle.Pick up a copy of the Old car pricing guide,which gives a pretty fair description of different classes of old vehicles.For instance a true number one vehicle is as it came from the factory,and is not driven,it is trailered to car shows.But nowhere does it say a number one has to be completly original with every part or flake of paint it came from the factory with.Many of the number one trucks on display today were old farm trucks that were restored back to original condition.A good freind of mine who recently passed away had a 1957 Chevy convertible. This car was as close to a number one car as I have ever seen.When he sold it,it went for well over 100 grand.But heres the kicker it had a new top on it,new tires,and I imagine many new parts under the hood.However the major parts the engine,trans. rearend,etc, were all numbers matching to the car.I would imagine it was classified as a high number two.I doubt whether there is another 57 in the country that is in any better shape than that car. And when my freind owned it he drove it to shows,and cruisins.As for changing out a generator,doing a repaint,or putting new tires on a car or truck, that is pretty much just standard upkeep.
