After reading all these responses I see there are more categories than just original and not. I think it is common sense that all vehicles need routine maintenance. This includes replacing worn or broken parts, paint, upholstery, grease,oil, water. If one wants to say if you repainted your car it is no longer original then the first time you change oil it is no longer original which, of course, is ridiculous. Hemmings has alway been the recognized authority on these things and they have categories for classifying our cars. I think we should not find ways to separate our cars. We all have some awesome cars in there own way. Amazing restorations. Fine example of an original. Daily drivers showing wear but being driven. Mine is more original than yours sounds a lot like school kids saying my dad can beat up your dad.
