It is an SC so that would be '78-'83.  Not a US version as Grant pointed out though the bumpers are wide in the rear.

that is about what it takes to get these cars off the road for good.  Otherwise they are bullet proof.  Note how the door for the driver is open w/o issues.  He is fine I would bet.  My guess is he was standing still and someone hit him?  Note there are NO skid marks and he is not in a wall to the left which is where he is heading (pushed).  Something ran over the top right front of his car.  Sucks to be standing still and hit.  The car or your skills can't help you in any way.

Parts from the car alone would still be worth a small fortune.  Sad to see one go though.
