Google: james dean car crash
Click on images. Not much left of the car.
I bet they still have not fixed the road intersection in all these years.
I thought I read that the car toured carnivals and car shows for years afterwards. Of course people can make their own “James Dean Death Car”.
The real Bonnie and Clyde car was toured around but I think at a point a fake one was also created. Certainly one in a car museum is a recreation.
