Let's say that I have a very old car, install scrapped, recicled, off-the-shelf and/or handcrafted components, and effectively create a brand new car, completely different fron the original one, both in terms of specifications, equipment and possibily even aesthetics.
Given that all security, quality, environmental and legal requirements required by the country's legislation are met, does a process to legally register and drive this car on the public road exist? (so obtain a license plate and such)
Clearly car manufacturers have this process, but my guess is that it involves thousands of hours of testing and millons of euros spent, so that makes me raise some doubts on the feasibility for an individual.
I live in Europe, but I'm also interested in the situation in other parts of the world, where I assum there is more "freedom" in this sense.
