^ been this way for years. I've been at LKQ's largest yard (Akron, OH) several times for work, have seen them scrap train loads of cars, including cars without a mark on them. They also buy things like magazine test vehicle, vehicles used in ads, etc. They have to film the process of dismantling the vehicle and provide that video to the OEM. Also, if there were any prototype/non-production parts, those must be removed and returned to the OEM. I remember watching them cut up three 3rd Gen WS6 Trans Ams that GM had used to test a differently designed rear seat. They had to remove the seats and return them to GM, and then cut up the car. Guy with the plasma cutter was having a blast cutting those cars in half.
