Looks like the guy parts out cars on ebay - hummers and such. In most states if you part out cars as a business you have to be a registered auto recycler....and that registration can be lost by selling on totalled cars as fixers.
I would guess it was sold to him (or somebody else upstream) as a "parts car only" but it now being presented as a fixable driver.
Movie studios (and the constructors) don't want liability created by way of old props being sold on, so they have strict policies about what happens to stuff like this. Often, these things are built for a specific movie scene and are not made for road use, so those policies are good and there for a reason.
