All cars have to be tested. My Dad used to work at a place called Calspan in Buffalo NY and they had a large number of Crash Tested vehicles out in the back lot. Part of the work they do there. They are kept for years in case a question ever comes up. I remember a couple of brand new blue Trans Am's back there in the '70's. That was like "WTF is up with that"? Sad but inevitable.:( A small price to pay for safety.
