I bet for every example there's a hundred more that are just not registered and or are registered as something else.

It's like machine guns, you're not paying for the hardware. You're paying to not have the state send a squad of thugs to shoot you for not getting permission. People don't want the permission. They want the hardware. So they just get the hardware and keep it on the down low.

Also, everyone in automotive who isn't an OEM or in the emissions racket (i.e. the two groups benefitting) absolutely hates the government and this is exactly the kind of "interesting" vehicle junkyard people would save for their own personal golf cart use. Usually OEMs are super anal about making sure stuff actually gets crushed but they shat out too many EV1s into the world to do a good job of that like they do for prototypes, test mules and other stuff with low double digit production runs if that.
