I wonder how many modules, parts and harnesses would be required to turn a classic or autopilot 1 car into a autopilot 2.0 car. Assuming you have a donor and the ability to reprogram the various modules. Someone such as rich rebuild could in theory do it, but you would have to strip the car to its shell and just transfer the parts from a donor car. I was thinking of the feasibility of doing such a thing on a early signature red Model S. Perhaps one day if i can find a example with bad pack or motors and buy a salvaged donor. I may attempt to do it,
