Couldn't find crash tests of classic Cads, though, but I remember seeing one from a program on car safety, from the segment on air bags, since when they became big again in the early 90s people were concerned with how they would age. The pulled an old DeVille with ACRS from the junk yard (imagine the ordeal to find that!) and crash-tested it, the ACRS worked like a charm! Those old GM Air Cushion Restraint System cars actually had two-stage air bags! I'd love to have one of those cars...
