It's an "Erlkönig" (prototype for street testing), i think it would be pretty hard to register something like that for regular street use anyway.
The sculpture is called "Verdichtung"(= compression), its intention is to show that time only moves in one direction and isn't reversible
I also think it's something special, i never saw a crushed, entire 997 - just because nobody would be crazy enough to do that without removing all expensive parts, and as it's a Porsche, everything is expensive somehow
