They did a little odd.
I just tried several motorcycle salvage search tools and the first couple I tried didn't even list Polaris as a motorcycle brand.
I tried a Google search for motorcycle salvage yards within XX miles of my location and was surprised at how many places showed up within 100 or so miles from my home. Unfortunately, it seems motorcycle salvagers may not consider the Slingshot as a motorcycle and auto salvagers don't either! Good Luck!
