I went a long way down this route a year or so ago, having found an absolutely perfect 1986 porsche 911 "donor car," however the amount of regulation the car needed to comply with, the engineering time and the expense of the motors, batteries and controllers (that would have to be custom made to fit the car) meant that I was going to spend a quarter million all in. I could have saved maybe a third of that taking a used car off a scrapheap, but then it defeats the point of ending up with a car I actually wanted to drive.
