In the US you can do that already, but I wonder if it will be cheaper for decades to come to purchase a used commercial vehicle (typically a pickup truck or van) and overhaul it as long as the frame is good. The amount of information mechanics can find online these days about some pretty esoteric rebuilding procedures boggles my mind. What I see folks refurbishing in Eastern Europe, Africa, South America, Pakistan and elsewhere to keep on the roads is astonishing (albeit only possible in current markets as we implement them with high-skill, low-cost labor). There are a hell of a lot of light-to-heavy duty diesel pickups in the US and the aftermarket offerings are enormously deep and broad, for example. I imagine that will take awhile to fade away, and if metrology gets advanced and cheap enough, and integrates well enough with machinists on the floor, I can see a possible future where these parts live on in electronic form to the point where reproducing them from scratch gets into the realm of economically feasible.
